Amber went to her local gym to work out. The ratio of her time doing cardio to weight lifting was 13:11. Amber spent 44 minutes lifting. How much time did she do cardio?

Answer = 52 minutes

You are given a ratio of cardio:weight lifting, 13:11.

You are also given how long she spent weight lifting, which is 44 minutes.

To find out how much she spent doing cardio, you first figure out how to get from 11 mins to 44 mins in weight lifting.

13:11 (Times by 4 because 11 can go into 44, by 4.)

Cardio : Weight lifting

52:44

So Amber spent 52 minutes doing cardio and 44 minutes doing weightlifting.
