Question

True or false 120% of a whole number is always greater than the number? and why?

Answer 1

Since whole numbers are positive integers, then it follows that a positive integer multiplied by 1.2 will be greater than the original by 20%. 

Answer 2

I can only use math to explain it. What is 100%?
100% = $\frac{100}{100}$ 
percent means per 100.
so 120% = 120/100 = 1.2
120% of a whole number. For example 120% * 10 = $\frac{120}{100} * 10$ = 12
is it greater than 10.
