EduRev Class 6 answered |
Converting 2 rupees and 5 paise to decimal
- To convert 2 rupees and 5 paise to decimal, we need to consider that 1 rupee is equal to 100 paise.
- Therefore, 2 rupees is equal to 200 paise.
- Adding 200 paise to 5 paise gives us a total of 205 paise.
- To convert paise to rupees, we divide the total paise by 100.
- Therefore, 205 paise is equal to 2.05 rupees.
- Hence, 2 rupees and 5 paise can be written as Rs 2.05 in decimal form.

Kunal Mehta answered |
who has a height of 150 cm has a height of 1.5 meters.
You can convert centimeters to meters simply by dividing the cm by 10, and vice versa for converting meters to centimeters. For example, 10 cm / 10 is .1 meters, and 1 m / 10 is 100 cm.

Nishtha Mukherjee answered |
To find which decimal number is the same as 1/2, we need to convert the fraction into a decimal.
1/2 as a decimal is 0.5.
Let's analyze the options given:
a) 0.34 - This decimal number is not equal to 1/2.
b) 0.50 - This decimal number is equal to 1/2.
c) 0.75 - This decimal number is not equal to 1/2.
d) 3.4 - This decimal number is not equal to 1/2.
Therefore, the correct answer is option b) 0.50.
Explanation:
- Option a) is 0.34, which is less than 1/2 because 34 is less than 50.
- Option b) is 0.50, which is equal to 1/2 because 50 is equal to 50.
- Option c) is 0.75, which is greater than 1/2 because 75 is greater than 50.
- Option d) is 3.4, which is a whole number and not a decimal equivalent of 1/2.
By comparing the options to the decimal equivalent of 1/2, we can clearly see that option b) 0.50 is the correct answer.
1/2 as a decimal is 0.5.

Gunjan Lakhani answered |
To convert meters to kilometers, divide the number of meters by 1,000, since 1 kilometer equals 1,000 meters.
For 88 meters: 88/1000 = 0.088 kilometers.
Thus, 88 meters is equivalent to 0.088 kilometers.
The correct answer is option B: 0.088 km.

Rahul Kumar answered |
Align the decimal places for addition:
0.015 + 4.250 + 12.300
Add the values:
0.015 + 4.250 = 4.265
4.265 + 12.300 = 16.565
0.015 + 4.250 + 12.300
Add the values:
0.015 + 4.250 = 4.265
4.265 + 12.300 = 16.565

Anoushka Chavan answered |
Solution:
To make the given equation true, we need to express the mixed number 7 8/? as an improper fraction and then multiply the denominator of the fraction with 7 and add the numerator to get the equivalent fraction of 7.8.
Let's convert 7 8/? to an improper fraction:
7 8/? = (7 × ? + 8)/? = (7? + 8)/?
Now, we need to find the value of ? such that (7? + 8)/? = 7.8
Multiplying both sides by ?, we get:
7? + 8 = 7.8 × ?
7? = 7.8 × ? - 8
? = (7.8 × ? - 8)/7
Now, we can try each option given in the answer choices to find the value of ? that satisfies the equation.
a) ? = 1
(7.8 × 1 - 8)/7 = -0.2/7 ≠ 1
b) ? = 8
(7.8 × 8 - 8)/7 = 54.4/7 ≠ 8
c) ? = 10
(7.8 × 10 - 8)/7 = 70/7 = 10
d) ? = 100
(7.8 × 100 - 8)/7 = 772/7 ≠ 100
Therefore, the correct answer is option 'C' i.e. 10.
To make the given equation true, we need to express the mixed number 7 8/? as an improper fraction and then multiply the denominator of the fraction with 7 and add the numerator to get the equivalent fraction of 7.8.

7 8/? = (7 × ? + 8)/? = (7? + 8)/?
Now, we need to find the value of ? such that (7? + 8)/? = 7.8
Multiplying both sides by ?, we get:
7? + 8 = 7.8 × ?
7? = 7.8 × ? - 8
? = (7.8 × ? - 8)/7
Now, we can try each option given in the answer choices to find the value of ? that satisfies the equation.
a) ? = 1
(7.8 × 1 - 8)/7 = -0.2/7 ≠ 1
b) ? = 8
(7.8 × 8 - 8)/7 = 54.4/7 ≠ 8
c) ? = 10
(7.8 × 10 - 8)/7 = 70/7 = 10
d) ? = 100
(7.8 × 100 - 8)/7 = 772/7 ≠ 100
Therefore, the correct answer is option 'C' i.e. 10.

Charvi Chauhan answered |
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.

Sagar Sharma answered |
The value of a digit changes as it moves from the right to the left in a place value chart. Let's understand this concept in detail:
Understanding Place Value:
In our number system, each digit has a specific value depending on its position in a number. This is known as place value. The value of a digit is determined by its position in relation to the decimal point.
For example, in the number 345.67:
- The digit 7 is in the ones place and has a value of 7.
- The digit 6 is in the tenths place and has a value of 6/10 or 0.6.
- The digit 5 is in the hundredths place and has a value of 5/100 or 0.05.
- The digit 4 is in the thousands place and has a value of 4 * 1000 or 4000.
- The digit 3 is in the ten thousands place and has a value of 3 * 10,000 or 30,000.
Increasing Value:
As we move from right to left in a place value chart, the value of a digit increases by 10 times. This is because each digit's value is 10 times greater than the digit to its right.
For example, consider the number 345.67 again:
- The digit 5 is 10 times greater than the digit 4.
- The digit 4 is 10 times greater than the digit 3.
So, as we move from right to left, the value of each digit increases by a factor of 10.
Summary:
In a place value chart, the value of a digit changes as it moves from the right to the left. The value of a digit increases by 10 times as we go from right to left. This is a fundamental concept in our number system and helps us understand the relative values of digits in a number.

Understanding the Comparison
To compare the numbers 0.01 and 0.3, we first need to understand their values in the decimal system.
Decimal System Basics
- The decimal system is based on powers of ten.
- Each digit to the right of the decimal point represents a fraction of ten.
Placing the Numbers
- 0.01 means one hundredth (1/100).
- 0.3 means three tenths (3/10).
Converting to a Common Denominator
- To compare the two numbers, we can convert them to the same denominator:
- 0.01 = 0.01
- 0.3 = 0.30 (adding a zero to the right does not change its value).
Direct Comparison
- Now we can directly compare:
- 0.01 is equivalent to 0.01
- 0.3 is equivalent to 0.30
When lined up:
- 0.01 < 0.30="">Conclusion
Thus, we can see that 0.01 is less than 0.3. Therefore, the correct answer is option 'B' (b <).>

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.
