Question

Round 224.91 to the nearest whole number.

Answer 1

Whole numbers are numbers without a decimal. When we round up a number with a decimal, any number after the dot which is more than 5 is considered as 1. Less than 5 is not taken into account.
So the nearest whole number is 225

Answer 2

Whole numbers do not include decimals. so for the value higher than 5, 1 is added to a number right before that. In this situation 9 is greater than 5 so, 1 is added in 4. thus 4+1=5
225 is the whole number
