Given :

The difference of 13.256 and 7.93

To find :

Round off the difference's of 13.256 and 7.93 to the nearest hundredths

Discard all digits to the right of the nth place , if the discarded number is less than half a unit in the nth place , leave the nth digit unchanged ; if the discarded number is greater than half a unit in the nth place , add 1 to the nth digit .

If the discarded digit is exactly half an unit in nth digit leaving the nth digit unaltered if it is an even number but increase it by 1 if it is an odd number

Solution :

Step 1 of 2 :

Calculate the difference of 13.256 and 7.93

The difference of 13.256 and 7.93

= 13.256 - 7.93

= 5.326
