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;

[tex] \frac{90}{15} = \frac{y}{7} [/tex]

Simplify the left ratio:

[tex] \frac{6}{1} = \frac{y}{7} [/tex]

Cross multiply:

[tex]6 \times 7 = 1 \times y[/tex]

[tex]42 = y[/tex]

Therefore the missing term is 42.
