## To Divide a Fraction by a Whole Number:

- Step 1. Multiply the bottom number of the fraction by the whole number
- Step 2. Simplify the fraction (if needed)

### Example:

\frac{1}{2} ÷ 3

Step 1. Multiply the bottom number of the fraction by the whole number:

\frac{1}{2 × 3} = \frac{1}{6}

Step 2. Fraction is already as simple as possible, so no need for step 2. Answer:

### With Pen and Paper

And here is how to do it with a pen and paper (press the play button):

### Does it make sense?

Does \frac{1}{2} ÷ 3 really equal \frac{1}{6} ?

Well look at the pizzas below ...

When half a pizza is divided into 3 equal parts, each person gets one sixth of a whole pizza.

A Half: | Divided by 3: | Answer: 1/6 |

### Example:

\frac{2}{5} ÷ 4

Step 1. Multiply the bottom number of the fraction by the whole number:

\frac{2}{5 × 4} = \frac{2}{20}

Step 2. Simplify the fraction:

\frac{2}{20} = \frac{1}{10}

And that is all we have to do.
