Answer:

See the entire solution process below:

Explanation:

First, we can rewrite #7 1/2# as #7.5#.

"Percent" or "%" means "out of 100" or "per 100", Therefore 7.5 percent can be written as #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# while keeping the equation balanced:

#n = 7.5/100 xx 12#

#n = 90/100#

#n = 0.9# or #n = 9/10#
