Just divide by 100.

So 10% is 10/100 = 1/10
and 20% = 20/100 = 1/5

Percent means "out of 100." We can use the percent symbol (%) as a handy way to write a fraction with a common denominator of 100.

For example, 50% can be written as 50/100 in fraction.
or its simplest form is 1/2. And to change it to decimal, just divide the numerator by the denominator, and you will get 0.5.

A ratio is a quantity that denotes the proportional amount of one quantity relative to another.

Fractions and percentages are both specific applications of ratios. Fractions relate the part (the numerator) to the whole (the denominator) while percentages indicate parts per 100.

Thus in changing percentages to ratio form, first you change it to fraction, and then express the fraction to ratio.

Example:
50% = 50/100 = 50:100 or 1:2
85% = 85/100 = 85/100 or 17 : 20

Any percent is just the number of the percent over 100. So for instance, 56% is 56/100, 45% is 45/100. You can simplify the ratio or fraction to determine the simplest form of the ratio.
