Question

Students volunteering at a charity event work 1/2- hour shifts.Zack volunteered for 4 hours.He incorrectly divided one half by four to find the number of shifts he worked. How should zack have calculated the number of his shifts

Answer 1

Answer:

He should have divided 4 by  $\frac{1}{2}$:

$shifts=\frac{4}{\frac{1}{2}}\\\\shifts=8$

Step-by-step explanation:

You know that the students work $\frac{1}{2}$-hour shifts at the charity event and Zack worked in the event for four hours.

Then, to calculate the number of shifts he worked, he should not have divided $\frac{1}{2}$ by 4. He should have divided 4 by  $\frac{1}{2}$.

Let's make the correct procedure to calculate the number of shifts Zack worked  at the charity event. This is:

$shifts=\frac{4}{\frac{1}{2}}\\\\shifts=8$

Therefore, he worked 8 shifts.
