How to work out percentages - Step by Step

Here are the solutions to the questions stated above:

1) What is 45% of 7/8?

Always use this formula to find a percentage:

% / 100 = Part / Whole replace the given values:

45 / 100 = Part / 7/8

Cross multiply:

45 x 7/8 = 100 x Part, or

39.375 = 100 x Part

Now, divide by 100 and get the answer:

Part = 39.375 / 100 = 3.15

2) 45 is what percent of 7/8?

Use again the same percentage formula:

% / 100 = Part / Whole replace the given values:

% / 100 = 45 / 7/8

Cross multiply:

% x 7/8 = 45 x 100

Divide by 7/8 and get the percentage:

% = 45 x 100 / 7/8 = 5142.8571428571%
