Answer 2

a) 1/2 + 1/4

To add fractions, we need to find a common denominator. In this case, the common denominator is 4. So, we have:

1/2 + 1/4 = 2/4 + 1/4 = 3/4

Therefore, 1/2 + 1/4 = 3/4.

b) 2/5 + 3/10

To add fractions, we need to find a common denominator. In this case, the common denominator is 10. So, we have:

2/5 + 3/10 = 4/10 + 3/10 = 7/10

Therefore, 2/5 + 3/10 = 7/10.

c) 3/16 + 1/2

To add fractions, we need to find a common denominator. In this case, the common denominator is 16. So, we have:

3/16 + 1/2 = 3/16 + 8/16 = 11/16

Therefore, 3/16 + 1/2 = 11/16.

d) 5/9 + 1/3

To add fractions, we need to find a common denominator. In this case, the common denominator is 9. So, we have:

5/9 + 1/3 = 5/9 + 3/9 = 8/9

Therefore, 5/9 + 1/3 = 8/9.

e) 3/4 + 1/6

To add fractions, we need to find a common denominator. In this case, the common denominator is 12. So, we have:

3/4 + 1/6 = 9/12 + 2/12 = 11/12

Therefore, 3/4 + 1/6 = 11/12.

f) 5/9 + 7/12

To add fractions, we need to find a common denominator. In this case, the common denominator is 36. So, we have:

5/9 + 7/12 = 20/36 + 21/36 = 41/36

Therefore, 5/9 + 7/12 = 41/36.

g) 3/10 + 2/15

To add fractions, we need to find a common denominator. In this case, the common denominator is 30. So, we have:

3/10 + 2/15 = 9/30 + 4/30 = 13/30

Therefore, 3/10 + 2/15 = 13/30.

h) 11/20 + 2/15

To add fractions, we need to find a common denominator. In this case, the common denominator is 60. So, we have:

11/20 + 2/15 = 33/60 + 8/60 = 41/60

Therefore, 11/20 + 2/15 = 41/60.
