Question

The ratio of Scott’s age to Georgia’s age to Fiona’s age is 11:6:7 The ratio of Oscar’s age to Georgia’s age is 3:4

Find the ratio of Fiona’s age to Oscar’s age.

Answer 1

Scott's age is 11x

Georgia's age is 6x = 4y

therefore y=1.5x

Fiona's age is 7x

Oscar's age is 3y

therefore 3(1.5x)=4.5x

Fiona's age: Oscar's age

7x : 4.5x

7 : 4.5
