What is the concept of rounding off an integer value ?

For rounding off after a decimal place, we see the value of the number after the decimal point. For rounding off we increment the place by one if the successor is greater than 5 and decrement by one if successor is less than 5.

Finding the sum of the given decimal -

The three given decimals are 2.798 , 8.874 and 3.907

The sum of the three decimals is

= (2.798 + 8.874 + 3.907) = 15.579

Now rounding off the given sum to 1 decimal place, we have 15.6 as 7 is more than 5 in the second decimal place

Now again rounding off the value to the nearest whole number, we have 16 as 6 is again more than 5 .

Thus the sum of the decimal rounding off to nearest whole number is 16
