d. 1 1/12

3. 1/4 + 11/16

a. 9/16
b. 1 1/16
c. 11/16
d. 15/16

4. 7/15 – 3/10

a. 1/6
b. 4/5
c.  1/7
d. 1 1/3

5. 17/23 – 15/23

a. 2
b. 1/11
c. 2/13
d. 2/23

6. 15/16 x 8/9

a. 5/6
b. 16/37
c. 2/11
d. 5/7

7. 3/4 x 5/11

a. 2/15
b. 19/44
c. 3/19
d. 15/44

8. 5/8 ÷ 2/3

a. 15/16
b. 10/24
c. 5/12
d. 1 2/5

9. 2/15 ÷ 4/5

a. 6/65
b.  6/75
c. 5/12
d. 1/6

10. 11/20 ÷ 9/20

a. 99/20
b.  4 19/20
c. 1 2/9
d.  1 1/9

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

for number 1, how does 13/12= 11/12 ?

1. Brian says:

yes you are correct – it appears to be 11/12 but is 1 1/12 (no space)!
