Yashvi Pillai answered |
**Explanation:**
A mixed fraction is a combination of a whole number and a proper fraction, where the numerator is less than the denominator. It is written in the form of a whole number followed by a fraction.
For example, 3 1/2 is a mixed fraction where 3 is the whole number and 1/2 is the fraction.
On the other hand, a proper fraction is a fraction where the numerator is less than the denominator. It does not have a whole number part.
For example, 1/2 is a proper fraction.
Now, let's consider the given statement: "Mixed fraction = Nearest Natural Number"
This means that when we have a mixed fraction, we need to find the nearest natural number that is closest to the value of the mixed fraction.
For example, if we have the mixed fraction 3 1/2, we need to find the nearest natural number to the value of 3 1/2.
The value of 3 1/2 is 3.5. The nearest natural number to 3.5 is 4.
Therefore, the nearest natural number to the mixed fraction 3 1/2 is 4.
Since the answer is a whole number (natural number) and not a fraction, the correct option is B) Proper fraction.
In summary, when we have a mixed fraction and we need to find the nearest natural number to its value, the answer will always be a proper fraction.

d)

Shivani Banerjee answered |
The correct answer is option 'A' - Like decimals.
Decimals are a way of representing numbers that are not whole numbers. They include a decimal point that separates the whole number part from the decimal part. The digits to the right of the decimal point represent a fraction of a whole number.
When comparing decimals, it is important to consider the number of decimal places they have. The number of decimal places refers to the number of digits to the right of the decimal point.
Decimals that have the same number of decimal places are called like decimals. For example, 0.25 and 0.75 have two decimal places, so they are like decimals. Similarly, 2.430 and 5.730 have three decimal places, so they are also like decimals. In both cases, the number of decimal places is the same, making them like decimals.
On the other hand, decimals that have a different number of decimal places are called unlike decimals. For example, 0.5 and 0.35 have different decimal places, so they are unlike decimals. Similarly, 3.2 and 5.67 have a different number of decimal places, so they are unlike decimals as well.
The reason why the correct answer is option 'A' - Like decimals is because decimals with the same number of decimal places are considered to be similar or like each other. This helps in comparing and performing operations on decimals more easily.
Understanding the concept of like and unlike decimals is important in various mathematical operations such as addition, subtraction, multiplication, and division. It allows us to align the decimal places correctly, making calculations more accurate.

Notes Wala answered |
0.005 ÷ 0.25 can be calculated by dividing 0.005 by 0.25. Here’s how to understand this division:
- When you divide a smaller number by a larger number, the result is usually less than 1.
- In this case, 0.005 is much smaller than 0.25.
- The actual division gives you a decimal number.
The calculation can be simplified:
- 0.005 divided by 0.25 equals 0.02.
- This means that 0.005 is 2% of 0.25.
Thus, the result of the division is 0.02.

Manoj Desai answered |
Weight of the basketball in milligrams: 700,000 mg
To determine if the weight of the basketball is less than, greater than, or equal to 700 grams, we need to convert the weight from milligrams to grams.
1. Conversion of milligrams to grams:
We know that 1 gram (g) is equal to 1,000 milligrams (mg).
Therefore, to convert milligrams to grams, we divide the weight in milligrams by 1,000.
Weight in grams = Weight in milligrams / 1,000
2. Calculating the weight of the basketball in grams:
Weight in grams = 700,000 mg / 1,000
Weight in grams = 700 g
Now, we can compare the weight of the basketball to 700 grams.
Comparison:
The weight of the basketball (700 g) is equal to 700 grams.
Therefore, the correct answer is option 'C': Equal to 700 g.
Explanation:
The weight of the basketball is given in milligrams, so we need to convert it to grams for a meaningful comparison. By dividing the weight in milligrams by 1,000, we obtain the weight in grams, which is 700 g. Since the weight of the basketball is exactly 700 grams, it is equal to 700 g, and option 'C' is the correct answer.

Therefore, to convert milligrams to grams, we divide the weight in milligrams by 1,000.
Weight in grams = Weight in milligrams / 1,000
2. Calculating the weight of the basketball in grams:
Weight in grams = 700,000 mg / 1,000
Weight in grams = 700 g
Now, we can compare the weight of the basketball to 700 grams.
Comparison:
The weight of the basketball (700 g) is equal to 700 grams.
Therefore, the correct answer is option 'C': Equal to 700 g.

Understanding Fractions and Decimals
To convert a fraction into decimal form, you divide the numerator (top number) by the denominator (bottom number). In this case, we have:
- Numerator: 12
- Denominator: 100
Calculating the Decimal
To find the decimal form of 12/100, perform the division:
- 12 divided by 100 equals 0.12.
This means:
- When you divide 12 by 100, you get 0.12.
Why Option C is Correct
Let’s examine the answer choices:
- a) 1.2 – This is incorrect because it suggests that 12/100 is equal to twelve-tenths, which is much larger than the fraction.
- b) 12.0 – This option is incorrect because it represents the whole number twelve, which does not correspond to the fraction 12/100.
- c) 0.12 – This is correct! As calculated, 12/100 equals 0.12.
- d) 0.012 – This is also incorrect because it suggests a much smaller value, representing twelve-thousandths instead of twelve-hundredths.
Conclusion
Therefore, the decimal form of 12/100 is indeed:
- 0.12 (Option C).
This conversion is useful in many real-life applications, such as understanding percentages and measurements, making it an essential skill in mathematics.

Shanaya Sharma answered |
Multiplying and dividing by 1000 in LHS, we get-
(144*1000) / (0.144*1000) = 14.4 / x
144000 / 144 = 14.4 / x
1000 = 14.4/x
x = 14.4/1000
x = 0.0144
(144*1000) / (0.144*1000) = 14.4 / x
144000 / 144 = 14.4 / x
1000 = 14.4/x
x = 14.4/1000
x = 0.0144

Prasad Kulkarni answered |
Understanding Decimal Comparison
When comparing decimals, it's important to look at the digits from left to right. Each digit's place value helps determine which number is greater.
Step-by-Step Comparison
- Identify the Numbers:
We have 0.65 and 0.56.
- Compare the Whole Numbers:
Both numbers are less than 1, so we focus on the digits after the decimal point.
- Examine the Tenths Place:
- In 0.65, the tenths digit is 6.
- In 0.56, the tenths digit is also 5.
Here, 6 (from 0.65) is greater than 5 (from 0.56).
- Conclusion from Tenths Place:
Since the tenths digit of 0.65 is greater than that of 0.56, we can conclude that 0.65 is greater.
Final Verification
- Comparing the Hundredths Place:
- In 0.65, the hundredths digit is 5.
- In 0.56, the hundredths digit is 6.
Although 6 is greater than 5, the comparison was already determined by the tenths place.
- Overall Conclusion:
Since the tenths digit of 0.65 is larger, 0.65 is indeed greater than 0.56.
Correct Answer
- Therefore, the correct answer is option 'A': 0.65 is greater than 0.56.
When comparing decimals, it's important to look at the digits from left to right. Each digit's place value helps determine which number is greater.

Final Verification
- Comparing the Hundredths Place:
- In 0.65, the hundredths digit is 5.
- In 0.56, the hundredths digit is 6.
Although 6 is greater than 5, the comparison was already determined by the tenths place.
- Overall Conclusion:
Since the tenths digit of 0.65 is larger, 0.65 is indeed greater than 0.56.
Correct Answer
- Therefore, the correct answer is option 'A': 0.65 is greater than 0.56.

Aarav Sharma answered |
To express 3 kg 50 gm as kilograms, we need to convert the grams into kilograms.
1 kilogram is equal to 1000 grams.
So, 50 grams is equal to 50/1000 = 0.05 kilograms.
To express 3 kg 50 gm as kilograms, we add the converted grams to the given kilograms.
3 kg + 0.05 kg = 3.05 kg
Therefore, the correct answer is option 'C' which is 3.050 kg.
1 kilogram is equal to 1000 grams.
So, 50 grams is equal to 50/1000 = 0.05 kilograms.
To express 3 kg 50 gm as kilograms, we add the converted grams to the given kilograms.
3 kg + 0.05 kg = 3.05 kg
Therefore, the correct answer is option 'C' which is 3.050 kg.
