At her health club, Elke likes to use exercise bikes and weights. She spent 3/4 hour on the bikes and 1/5 hour less than that on the weights. How much time does she spend on the weights? Simplify answer if possible

If you would like to know how much time does Elke spend on the weights, you can calculate this using the following steps:

3/4 hour = 3/4 * 60 minutes = 45 minutes on the bikes

1/5 hour = 1/5 * 60 minutes = 12 minutes

12 minutes less than 45 minute: 45 - 12 = 33 minutes on the weights

The correct result would be 33 minutes.
