When a rectangle is divided into 10 equal parts, each part is known as one tenth or 1/10.

In this rectangle, there are ten equal squares and so each square is one tenth of the rectangle.

This rectangle has 3 tenths or 3/10 shaded and 7 tenths or 7/10 unshaded.

Does that make sense?

Let's have a go at some questions now and see how we get on.
