Question

Ryanne is 14. her brother's age is three more than half her age. how old is her brother?

Answer 1

Ryanne = 14
half her age : 14 ÷ 2 = 7
three more : 7 + 3 = 10
Her brother is 10 years old.

Answer 2

10 years old

Explanation:

I will use the letter r to denote Ryanne's age:

r = 14

And according to the problem, her brother's age is THREE MORE THAN HALF HER AGE

so, we start by finding how much is half of Ryanne's age:

r/2 = 14/2 = 7

and next, we find that three more than half her age is:

7 + 3 = 10

Her brother is 10 years old
