Understanding the Problem
To find what needs to be subtracted from 7.3 to reach 0.867, we can set up the equation:
7.3 - x = 0.867
Here, "x" represents the value that we need to find.
Rearranging the Equation
To isolate "x", we can rearrange the equation:
x = 7.3 - 0.867
Next, we perform the subtraction to find the value of "x".
Performing the Calculation
Let's break down the subtraction step-by-step:
- First, write down the numbers clearly:
- 7.3
- 0.867
- Align the decimal points and perform the subtraction:
- Convert 7.3 to 7.300 for easier calculation.
Now, subtract:
7.300
- 0.867
__________
6.433
Thus, x = 6.433.
Conclusion
The value that needs to be subtracted from 7.3 to obtain 0.867 is 6.433.
Therefore, the correct answer is option b) 6.433.

Subtracting Decimal Numbers:
To subtract decimal numbers, align the decimal points and then subtract as you would with whole numbers.
Calculation:
Given: 3 - 0.007
Aligning the decimal points, we get:
3.000
- 0.007
--------
2.993
Therefore, 3 - 0.007 equals 2.993.
Therefore, the correct answer is option D.

Understanding the Problem
To convert the weight from kilograms and grams into a single unit (kilograms), we need to know the relationship between kilograms and grams.
- 1 kilogram (kg) = 1000 grams (g)
Breaking Down the Given Weight
The given weight is 2 kg and 57 g. We can convert it as follows:
- Convert grams to kilograms:
57 g can be converted to kilograms by dividing by 1000.
57 g = 57 / 1000 kg = 0.057 kg
- Add the two weights together:
Now, we can add the kilograms:
2 kg + 0.057 kg = 2.057 kg
Final Conversion
Thus, when you combine both the kilograms and the converted grams, the total weight is:
- Total weight = 2.057 kg
Selecting the Correct Answer
Now, let's look at the options provided:
a) 2.57 kg
b) 2.570 kg
c) 2.057 kg
d) None of these
From our calculations, the correct answer is:
- Option C: 2.057 kg
Conclusion
In summary, by converting grams to kilograms and then summing them, we arrive at the total weight of 2.057 kg, confirming that the correct choice is option C.

Total earning during three days
To find the total earning during the three days, we need to add up the earnings of each day.
Given:
Earning on the first day = Rs 302.80
Earning on the second day = Rs 379.20
Earning on the third day = Rs 297.60
To find the total earning, we add these amounts together:
Total earning = Rs 302.80 + Rs 379.20 + Rs 297.60
Calculating the total earning:
Total earning = Rs 979.60
Therefore, the total earning during these three days is Rs 979.60.
The correct answer is option A) Rs 979.60.

EduRev Class 6 answered |
To compare the numbers, we need to consider their values:
- 5.005 is the smallest because it has the smallest decimal part.
- 5.05 comes next, as it has a larger decimal part than 5.005.
- 5.5 comes after 5.05, as 5.5 is greater.
- 5.555 is the largest number.
Thus, the correct order is: 5.005 < 5.05 < 5.5 < 5.555
Therefore, the correct answer is Option B.
