Example 1
Take a look at this shape and answer these three questions.

How many parts has it been divided into?
How many parts are shaded?
Are the parts equal?
✓ Here are the answers:
- The shape has been divided into five parts.
- One part, or 1 one-fifth, has been shaded.
- All the parts are equal.

Example 2
Here are 10 children in a group.

If you divided the group into 5 teams, how many children would be in each team?
Can you also divide them into 3 equal teams?
✓ There would be 2 children in each team, if you divided the group into 5 equal teams.

You can not divide the group into 3 equal teams, because there would be an unequal number of children in each team.

Example 3

This shape is one part of a whole. There are 4 equal parts to the whole.
What shape is the whole?
