Let's recall the basics of percentage.

- The term "percent" means per hundred(\(100\)) or for every hundred. This term has been derived from the Latin word per centum.
- The symbol (\(\%\)) is used for the term percent.

Example:

30 percent is written as 30\(\%,\) and it means that "30 out of \(100\)". That is \(\frac{78}{100}\).

**Fractional Equivalents of Commonly used Percentages**:

\(1\)\(\%\) \(=\) \(1/100\) | \(2\)\(\%\) \(=\) \(1/50\) | \(4\) \(\%\) \(=\) \(1/25\) | \(5\)\(\%\) \(=\) \(1/20\) |

\(8\)\(\%\) \(=\) \(2/25\) | \(10\)\(\%\) \(=\) \(1/10\) | \(12\)\(\%\) \(=\) \(3/25\) | \(15\)\(\%\) \(=\) \(3/25\) |

\(16\)\(\%\) \(=\) \(4/25\) | \(20\)\(\%\) \(=\) \(1/4\) | \(25\)\(\%\) \(=\) \(1/4\) | \(40\)\(\%\) \(=\) \(2/5\) |

\(50\)\(\%\) \(=\) \(1/2\) | \(60\)\(\%\) \(=\) \(3/5\) | \(75\)\(\%\) \(=\) \(3/4\) | \(80\)\(\%\) \(=\) \(4/5\) |
