Question

Find the missing term of each equivalent ratio. 90:15=_____:7​

Answer 1

The missing term is 42.

EXPLANATION.

We want to find the missing term of the equivalent ratio. 90:15=_____:7

Let y be the missing term, then

90:15=y:7

We rewrite as fractions to get;

`(90)/(15) = (y)/(7)`

Simplify the left ratio:

`(6)/(1) = (y)/(7)`

Cross multiply:

`6 * 7 = 1 * y`

`42 = y`

Therefore the missing term is 42.
