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
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%.
25 * 0.20 = 5.
