Question

How do I know the porcentage of a fraction
And how do I turn itinot a decimal?

Answer 1

To turn a fraction into a percentage, set the fraction equal to a ratio out of 100. Then solve the proportion.
For example, what percent is 5/8?
Set 5/8 equal to a fraction with denominator 100 and unknown numerator, x, or x/100.
Now set the fraction equal to the ratio out of 100 and solve for x:
5/8 = x/100
8x = 5 x 100
8x = 500
x = 62.5, so 5/8 = 62.5%

Answer 2

To write a fraction as a decimal, just do long division:
5/8 = 5 divided by 8, or 8 into 5.
Do that long division, and you'll get the answer
