How do you calculate a percentage?

Calculating a percentage involves determining a part’s portion in relation to a whole and expressing it as a fraction of 100. To calculate a percentage:

Identify the part you want to find a percentage of.
Divide the part by the whole.
Multiply the result by 100.

For example, if you have 75 out of 150:

Divide 75 by 150 to get 0.5.
Multiply 0.5 by 100 to get 50%.

So, 75 is 50% of 150.

Alternatively, if you have a percentage (20%) and a whole (200):

Divide 20 by 100 to get 0.2.
Multiply 0.2 by 200 to get 40.

Thus, 20% of 200 is 40.
