Whatpercent of his attempted free throws did Trevon make?1. Complete the proportion. Use a variable for the missing value.

Answer 1

We have the proportion:

$\frac{24}{40}=\frac{x}{100}$

We solve for the value missing as follows:

$\frac{24\cdot100}{40}=x\Rightarrow x=60$

So, the missing value is 60.
