Question

Oscar is 16 yrs old and his sister is 12. what will be the ratio of Oscar's age to his sister's age in 2 years?Write as a fraction in simplest form.

Answer 1

Oscar's age = 16
Sister's age = 12

Current year: 16 / 12
Simplest form: 4 / 3 ; both are divisible by 4.

2 years after: (16 + 2) / (12 + 2) = 18 / 14 ; add two years to both numbers.

Simplest form: of 18 / 14 is 9 / 7; both are divisible by 2.

Answer 2

16 to 12 and then you simply by 4 and you get 4/3.
