7-104.

When Malcolm hops 10 times down the hallway, he travels 12 feet. How many times would he need to hop to travel to his class, 90 feet away? Homework Help ✎

Set up a proportion.

$\text{\frac{10\; hops}{12\; feet} = \frac{{\it x}\;hops}{90\;feet}}$

900 = 12x

Divide both sides by 12 to figure out how many times Malcom would need to hop to travel to class.
