See the entire solution process below:

First, we can rewrite $7 \frac{1}{2}$ $7 1/2$ as $7.5$ $7.5$ .

"Percent" or "%" means "out of 100" or "per 100", Therefore 7.5 percent can be written as $\frac{7.5}{100}$ $7.5/100$ .

When dealing with percents the word "of" means "times" or "to multiply"
.
Finally, lets call the number we are looking for "n".

Putting this altogether we can write this equation and solve for $n$ $n$ while keeping the equation balanced:

$n = \frac{7.5}{100} \times 12$ $n = 7.5/100 xx 12$

$n = \frac{90}{100}$ $n = 90/100$

$n = 0.9$ $n = 0.9$ or $n = \frac{9}{10}$ $n = 9/10$
