Calculate the percentage of a number using the percentage formula              P% * X = Y

Example: What is 10% of 150?

First, convert the given problem to an equation using the percentage formula.

• P is 10%
• X is 150
• Hence the equation is 10% * 150 = Y

Convert 10% to a decimal by removing the percent sign and divide that by 100

• 10/ 100 = 0.10

Substitute 0.01 for 10% in the equation 

• 10% * 150 = Y 
• 0.10 * 150 = Y

Do the math 

• 0.10 * 150 = 15
• Y = 15
• So 10% of 150 is 15

Check the answer to the question, 

• Multiply 0.10 * 150 = 15

What is the history of the percentage?

The term percent is attributed to the Latin per centum, which refers to hundreds. But that is not right, the term from Italian Per Cento – for a hundred. The sign of percent is % by the gradual contraction of those words over centuries. 

Cento is the shape of two circles separated by horizontal lines where the symbol is derived from %.

The percent symbol is used in programming languages as an operator. It stands for the modulo operation.

In physics, the % symbol is used with a special meaning. Here it represents the relative error between the true value and the observed value found in the measurement.

There are two related signs:

• %oo – per myriad – per ten thousand
