Express these fractions and mixed numbers as a percent.
Mandarinka [93]
Okay so you start with 1/3. Fractions are just a fancy way of saying (in this case) 1 divided by 3. And if you do that you'll get .3333. After that to make it a percent you just move the decimal spot in front of the 3 over two places, getting 33.33%. With mixed numbers it's just one more step. So in this case 2 1/5 you would have to make it a normal fraction first so I got 11/5ths and here's how I got it. 2 1/5. Multiply the denominator (5) with 2. You get 10. Then add the numerator (1) to get 11. Tack on the 5 and you get 11/5. To make this a percent just do the same thing as the normal fractions... 11 divided by 5 to get 2.2. Move the decimal two places to the right to get 220%. Try the rest on your own and if you get confused ask... :)
