## Step by step guide to solve percent problems

- In each percent problem, we are looking for the base, or part or the percent.
- Use the following equations to find each missing section.
**Base**\(= \color{black}{Part} \ ÷ \ \color{blue}{Percent}\)

\(\color{ black }{Part} = \color{blue}{Percent} \ ×\)**Base**

\(\color{blue}{Percent} = \color{ black }{Part} \ ÷\)**Base**

### Percent Problems – Example 1:

\(2.5\) is what percent of \(20\)?

**Solution**:

In this problem, we are looking for the percent. Use the following equation:

\(\color{blue}{Percent} = \color{ black }{Part} \ ÷\) **Base** \(→\) Percent \(=2.5 \ ÷ \ 20=0.125=12.5\%\)
