A percent is a number relative to 100. Therefore, we want the number 100 in the ratio. In order to do that, we need to multiply BOTH numbers in the ratio by a number so that the second number of the new ratio is equal to 100. The first number of the new ratio is the percent. For example: 4:5 = [4*20]:[5*20] = 80:100 = 80%
12.8 To find it you just change the percent to a decimal and multiply it by the number. (ex. 0.16*80=12.8)
4 is 80% of 5
16. It takes 5x20 to equal 100. 80 divided by 5 equals 16.

To find 5 percent of a number, multiply the number by 0.05. In this instance, 0.05 x 80 = 4. Therefore, 5 percent of 80 is equal to 4.5% of 80 is 4.
5/4 = 1.25 = 125%
496 times 80/100, 4/5, .8, or 8% equals 396.8
0.5% of 80 is 2/5 or as 0.4
To find out what percent 80 is of 1600, you would divide 80 by 1600 and then multiply by 100. 80 divided by 1600 is 0.05, and when multiplied by 100, you get 5%. Therefore, 80 is 5% of 1600.
If 80 = 5% then 80/5 = 1%, which is 16. Then simply multiply by 100 to find 100%, which is 1600. So the answer is that 80 is 5% of 1600.

4 out of 5 is 80%. You can figure this out by taking 4 and dividing it by 5, which is 0.8, which is 80%. Or you can multiply 5 by 20 to get 100 and then multiply 4 by the same number which gives you 80, that would give you 80/100 or 80%.
