Introduction to percent (6th grade math lesson)

The main point... percentages are just FRACTIONS. "Five per cent" literally means "five per 100", or 5 / 100 -- five hundredths. Of course we can also write this as the decimal 0.05.

In this lesson, we first practice the concept of percent and write percents as fractions and as decimals and vice versa.

Then we convert fractions to percentages... there are TWO cases:
1. The fraction can easily be written as an equivalent fraction with 100 as the denominator.
2. If that is not the case, we need to use division (long division or a calculator).
