Answer: Hello mate!
Suppose you have a number of the form:
a.b where the dot is a decimal point, and we want to round this number to the nearest whole.
If the number b, is a number between 0 and 4, we round down, and the rounded number is equal to; a
if the number b is equal or bigger than 5, we need to round up, then the rounded number is (a + 1)
The number that we have here is 37.52
Here you need to look at the first number after the decimal point, in this case, is a 5, which means that we need to round up.
Then the rounded number is equal to 38.
