H/108=7/18<br> Please answer proportion

Oliga [24]

Answer:

<em>H </em>= 42

Step-by-step explanation:

18 ÷ 108 = $\frac{1}{6}$

7 ÷ $\frac{1}{6}$ = 42

You can check to make sure your answer is right by entering your proportions into a calculator. For example, $\frac{42}{108}=0.38888888888...$ and $\frac{7}{18}$ also equals $0.38888888888...$ so since they match, we know it is correct.

Make sure you know how to do your proportions without Brainly, that way you don't flunk your next quiz/test!
