3. WHAT IS A FRACTION?
When an object is divided into a
number of equalparts then each
part is called a fraction

4. numerator
denominator

5. Denominator
The denominator says how many
equalparts in the wholeobject
1
2
2 equal parts

6. How many equal parts are there in this shape?
What is the denominator of this fraction?

12. So, the denominator (on the bottom of
a fraction) tells us…
1

Denominator
How many there are in the whole object

13. numerator
The numerator says how many parts in
the fraction
1
2
1 part is
coloured in

14. How many equal parts are coloured in in this
shape?
What is the numerator of this fraction?
