2. What are Fractions?
• Fractions represent equal parts of a
whole or a group.
• When we divide a whole into equal parts,
each part is a fraction of the whole.

3. What are Fractions?
• When learning your fractions, the part
that is shaded is called the numerator.
• The total amount of parts in the whole
is called the denominator.

4. Numerator & Denominator
We call the top number the Numerator, it is
the number of parts we have.
We call the bottom number the Denominator, it
is the number of parts the whole is divided into.

5. Fractions Explained
Fractions also represent parts of a set or group.
For example,
There are total of 4 children.
2 out of 4 are girls. So, the fraction of girls is
two-quarters ( 2⁄4 ).
2 out of 5 are boys. So, the fraction of boys is
two-fifths ( 2⁄5 ).

6. Fractions Explained
Fractions can be broken down into a division
number sentence.
