Question

Aika spent a total of 80 minutes to complete her math and science homework. The ratio of the amount of time she spent to complete her science homework to the amount the time she spent to complete her math homework was 3 : 2. How many minutes did she spend on her math homework?

Answer 1

3+2 = 5
80/5 = 16
16 x 2 = 32 - math
16 x 3 = 48 - science
48 + 32 = 80 so she spent 32 minutes on math
