Decimal subtraction is like normal subtraction only. To do these kind of subtraction let us follow the steps.
Step1: Write the given decimal numbers one below the other so that the decimal point lined up.
Step2: Add zeros to the numbers which are having less digits after the decimal point so that both the numbers are of same length.
Step3:Let us do the subtraction normally, care should be taken to put the decimal point in the appropriate place.
Example:
Subtract 3.8 from 4.75
Solution:
Step1: Let us write the numbers one below other.
Step2:
Add zeros to the numbers which are having less number of digits after the decimal point so that both the numbers are of same length
Step3:
Let us do the subtraction normally.
So it is like 475-380 but with decimal point in the position.
Subtract 8.0003 from 0.55
Solution:
Step1: Let us write the numbers one below the other so that the decimal points lined up.
Step2: Add zeros to the number which is having less number of digits after the decimal point so that both the numbers become of equal length.
Step3: Let us do the subtraction normally.
So 8.0003-0.55=7.4503
Let us do some more problems.
Example:
Subtract 874-97.5555
Solution:
874.0000
- 97.5555
---------------
776.4445
So 874-97.5555 = 776.4445
Example:
Subtract 9.87 from 10
Solution:
10.00
- 9.87
---------
0.13
So 10-9.87 =0.13

Step 1: Write the given decimal numbers one below the other so that the decimal points of all the numbers lined up. Step2:Add zeros for the numbers which are having less digits after the decimal point. Step3: Now add the numbers starting from the right digit (like ordinary addition). We should not forget to put the decimal point at the appropriate place. |
