Answer:

$5\ shifts$

Step-by-step explanation:

we know that

To find out the number of shifts per day, divide the total number of hours per day the pool is open by each lifeguard's shift.

Convert to an improper fraction first

$7\frac{1}{2}\ h=\frac{7*2+1}{2}=\frac{15}{2}\ h$

$1\frac{1}{2}\ h=\frac{1*2+1}{2}=\frac{3}{2}\ h$

$(15/2)/(3/2)=15/3=5\ shifts$
