Question

Emily exercised from 4:05 p.m to 4:32 p.m. For what fraction of an hour did Emily exercise? Write the fraction in simplest form

Answer 1

First, we need to find out how many minutes she exercised for. Since she started at 4:05 and ended at 4:32, she exercised for 32-5=27 minutes. To write this as a fractional part of an hour, we need to write it as a fraction over 60 since there are 60 minutes in each hour. Then we'll reduce it to simplest form:

`(27)/(60)=(9)/(20)` of an hour.
