Question

Nicole is half as old as Donald. The sum of their ages is 72.

How old is Nicole, in years?

Answer 1

Your gonna divide 72 by 2 so therefore you get 36
So that equals to Nicole’s age

Answer 2

24 years

Explanation:

let Donald's age be x

then Nicole's age would be 1/2 * x = x/2

now, x + x/2 = 72

3x/2 = 72

3x = 72*2

x = 144/3 = 48

Donald's age is 48, so Nicole's age is 1/2 * 48 = 24 years.
