A **Pictogram** uses simple pictures to represent data. The total number of items in a set of data is shown by a number of pictures, where each picture represents one or more items.

An individual picture can be subdivided. If a picture represents four items, then a quarter of a picture represents one item.

A pictogram will always have a key, which indicates how many items each picture on the pictogram represents.

1. The pictogram shows the number of CDs sold at a charity event. How many pop CDs were sold?

Answer: 14

Each CD is worth 4. There are three full and one `frac(1)(2)` CD.

4 x 3`frac(1)(2)` = 14 CDs

2. The pictogram shows emails received over a day. The key to the pictogram has been left off the diagram. How many emails does each envelope represent, if 28 personal emails were received?

Answer: 8

3`frac(1)(2)` envelopes = 28 emails

Let *x* = number of emails in an envelope

`frac(7)(2)`*x* = 28

*x* = 8
