Question

Solve the proportion below. 5/x = 30/72 a.12 b.9 c.6 d.30

Answer 1

Hey there! :)

Answer:

x = 12.

Explanation:

Set the two proportions equal to each other:

`(5)/(x) = (30)/(72)`

Cross multiply to solve for x:

5 · 72 = 30 · x

360 = 30x

Divide both sides by 30:

360/30 = 30x/30

12 = x.

Therefore, the value of 'x' in this proportion is 12.

Answer 2

A. 12

Explanation:

Cross multiply:

30x = 72(5)

x = 360/30

x = 12
