1. Fractions
Addition
What will we learn today?
• addition of two related fractions
within one whole

2. Let’s recap what we have learnt
in the previous lecture.

3. Equivalent Fractions
Equivalent Fractions have the same value,
even though they may look different.

4. Looking the diagram, we can say that

5. Try these out!
1)½ + ½ =
2)⅛ + ⅛ =

6. Solutions
1)½ + ½=
2
2 =1 2 out of 2 parts gives 1 whole.
For addition, we do not add the
2)⅛ + ⅛ =
2 denominators.
Make sure the denominators of the
8 fractions are the same before you add
the numerators.
*Did you notice that the answer is
not in its simplest form?

7. ÷2
⅛+⅛=
2 1
8
= 4
÷2

8. Try these out!
List the next two equivalent fraction of the given fraction.
1)½=
2)⅛=

9. Try these out!
List the next two equivalent fraction of the given fraction.
1)½=
2 3
4 , 6
2)⅛=
2 3
16 , 24

10. 3 simple steps to add fractions:
• Step 1
– Make sure the bottom numbers
(denominators) are the same
• Step 2
– Add the top numbers (numerators), put the
answer over the denominator.
• Step 3
– Simplify the fraction (if necessary).

11. For example
Add the top numbers (numerators),
put the answer over the denominator.
Simplify the fraction (if necessary).
