Question

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

Answer 1

ANSWER

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;

$\frac{90}{15} = \frac{y}{7}$

Simplify the left ratio:

$\frac{6}{1} = \frac{y}{7}$

Cross multiply:

$6 \times 7 = 1 \times y$

$42 = y$

Therefore the missing term is 42.
