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

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:
of an hour.
