Answer: 12 is 4.76% of 252
Explanation: Fist thing to do when solving math is to read the question slowly and carefully. This question is asking 12 is what percent of 252. What you are going to do is turn that into a fraction:
12 / 252
Next, multiply the fraction by 100:
(12 / 252) x 100 = 4.76%
So if you buy an item at $252 with a $12 discount, you will pay $240 and get 4.76% discount cashback rewards.
Hope this helps! :)
