Question

Jade spent ⅓ of her math homework time working on word problems. What fraction of an hour did she spend working on word problems?

Answer 1

If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour

Explanation:

Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).

1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.
