The nearest whole number to the number 5.2 is 5.
Given number:
= 5.2
we can determine the whole number of any decimals using the properties that is,
if decimal part < .5 its nearest whole number is 0.
example = 0.5 whole number is 0.
if decimal part > 0.5 its nearest whole number is 1.
In this case,
= 5.2
decimal part = 0.2 < 0
so the nearest whole number is 5.
Therefore the nearest whole number to the number 5.2 is 5.
