Question

Write as a reduced fraction. 7.2%

Answer 1

7.2% is basically just 0.072. You move the decimal point to the side 2 times. Tjem upi write 0.072 as a fraction, which would be 72/1000. Simplifying this we can get 9/125.

Answer 2

What does % mean? It means "per cent" and what's a cent? a hundredth of a dollar! How many years are in a century? A hundred! Now we can see that this cent must mean something about 100. So in this case, it means "per cent" right? Well what does "per" mean to us? It's just division! Like, how many miles "per" hour. So just take 7.2/100 and you can see that you have a decimal with a fraction. That looks ridiculous. But remember, you can always multiply something by 1 without changing it, so if you multiply it by 10/10 that's still =1, you can get: 72/1000. But that's not simplest, since both of these are even numbers, we know we can divide by 2. So do it! Keep looking for other common factors until you can't any more, and then it's in its simplest terms.
