Adding Fractions with Denominators
that are Multiples
Aim: To add fractions with denominators that are multiples of the same number.
For the first fraction in each calculation, shade the correct number of columns. For the second
fraction, shade the correct number of squares. Use the diagram to calculate the answer.
Example: 12 + 14 = 34
1. 13 + 16 = 5. 56 + 12
1
=
2. 23 + 16 = 6. 14 + 12
5
=
3. 12 + 16 = 7. 25 + 15
2
=
