Write and solve a proportion to answer the question.

What percent of 25 is 12?

So percent means parts out of 100 so

x%=x/100

12/25

so luck that we can convert the bottom number to 100

12/25 times 4/4=48/100=48%

the answer is 48%

(the legit way is to simplify completely by using a calculator, then multiplply by 100
