How to work out percentages - Step by Step
Here are the solutions to the questions stated above:
1) What is 90% of 20?
Always use this formula to find a percentage:
% / 100 = Part / Whole replace the given values:
90 / 100 = Part / 20
Cross multiply:
90 x 20 = 100 x Part, or
1800 = 100 x Part
Now, divide by 100 and get the answer:
Part = 1800 / 100 = 18
2) What is 90 out of 20?
This question is equivalent to: "90 is what percent of 20?" Or What percent 90 is out of 20?
Use again the same percentage formula:
% / 100 = Part / Whole replace the given values:
% / 100 = 90 / 20
Cross multiply:
% x 20 = 90 x 100
Divide by 20 to get the percentage:
% = (90 x 100) / 20 = 450%
