Answer Key 

1. D
A common denominator is needed, number which both 3 and 12 will divide into. So, 8+5/12 = 13/12 = 1  1/12

2. C
A common denominator is needed, number which both 5 and 10 will divide into. So, 6+7/10 = 13/10 = 1 3/10

3. D
A common denominator is needed, number which both 4 and 16 will divide into. So, 4+11/16 = 15/16

4. A
A common denominator is needed, number which both 15 and 10 will divide into. So 14-9/30 = 5/30 = 1/6

5. D
Since the denominators are the same, we can just subtract the numerators, so 17-15/23 = 2/23

6. A
Since there are common numerators and denominators to cancel out, we cancel out 15/16 x 8/9 to get 5/2 x 1/3, and then we multiply numerators and denominators to get 5/6

7. D
Since there are no common numerators and denominators to cancel out, we simply multiply the numerators and then the denominators. So 3 x 5/4  x 11 = 15/44

8. A
To divide fractions, we multiply the first fraction with the inverse of the second fraction. Therefore we have 5/8 x 3/2, = 15/16

9. D
To divide fractions, we multiply the first fraction with the inverse of the second fraction. Therefore we have 2/15 x 5/4, (cancel out) = 1/3 x ½ = 1/6

10. C
11/20 x 20/9 = 11/1 x 1/9 = 11/9 = 1 2/9
