How to find the percent? 4 is what percent of 10

Always use this formula to find a percentage:

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

4 / 100 = Part / 10

Cross multiply:

4 x 10 = 100 x Part, or

40 = 100 x Part

Now, divide by 100 and get the

Part = 40 / 100 = 0.4

Use again the same percentage formula:

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

% / 100 = 4 / 10

Cross multiply:

% x 10 = 4 x 100

Divide by 10 and get the percentage:

% = 4 x 100 / 10 = 40%
