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.
