Question

A swimming pool is open for 12 hours each day. The lifeguards work shifts that are 3/4 hour long. How many shifts are there each day? Enter the correct answer in the box.

Answer 1

To find how many shifts of 3/4 hour long will be in 12 hours, we have to divide the total number of hours by the length of each shift:

$12\colon\frac{3}{4}=12\times\frac{4}{3}=16$

There will be 16 shifts each day
