Learn  Percentages  from Certified Online Pre-Algebra Tutor

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, “%” .We use the percent symbol (%) to express percent.

How do you get percentage of a number?

  • Multiply the number by the percent
  • Divide the answer by 100 (Move decimal point two places to the left)
  • Round to the desired precision

How do you get a percentage of an amount?

Let’s understand with an example:

1. Find 16% of $1600


16% of $1600
= 16/100 × 1600
= $256

A percent is 1 part out of 100.
1% is equal to 1/100 or 0.01.

How do you solve percent problems using a proportion ?

The proportion method works for all three types of percent problems.
  • What is 40% of 30?
  • 25% of what number is 75?
  • 5 is what percent of 4?


How do you get a percentage of an amount?

Let’s understand with an example:

1. What is 80% of 15?

The whole is 15.
The percent is 80%.

Let n represent the part.
Write a proportion to solve for n.

\frac{Part}{Whole} = \frac{Percent}{100}\Rightarrow\frac{n}{15} = \frac{80}{100}

100n = 80 x 15 \Rightarrow 100n = 1200


80% of 15 is 12.
