Question

Zach walked his dog for 7/8 hour. They spent 1/2 of the time at the beach. How much time did Zach and his dog spend at the beach?

Answer 1

Answer: $\frac{7}{16}hour$

Step-by-step explanation:

You know that the total time was: 7/8 hour

You also know that they spent 1/2 of the time at the beach.

Therefore, to calculate the time  Zach and his dog spend at the beach (which you can call x) , you must multiply both fractions (7/8 and 1/2).

Then, you obtain the following result:

$x=\frac{7}{8}hour*\frac{1}{2}\\\\x=\frac{7}{16}hour$
