How do you solve the problem '9 is what percent of 12'?

Answer 1

"Break the code" and convert from a word problem to an equation.

In math, "is" means equal, "percent symbol" means to divide by 100, and "of" means times, or multiply.

9 = ?% x 12

Now, if ?% x 12 = 9, then 9 divided by 12 must also be ?%, just like 3 x 2 = 6; and 6 divided by 3 = 2, or 6 divided by 2 = 3. So,

9 / 12 = 0.75

To express as a percent, multiply by 100 and then add the % symbol, or move the decimal 2 places to the right and then add the % symbol. 0.75 becomes 75% (which when you divide by 100, you get .75 again).

9 is 75% of 12. Check your work: 9 = .75 x 12 If this is true, then your answer is correct.

Answer 2

It is: 9/12 times 100 = 75%
