Add the following fractions.

3/8 + 5/12 =

for 3/8 you can times by 12 to make 36/96

for 5/12 you can times by 8 to make 40/96

now that they have the same denominators (bottoms), you can add them to make

36/96 + 40/96 = 76/96

simplified

= 38/48

=19/24

3/8 + b 5/12 = 8/20=2/5

3+5 = 8

8+12 = 20

common denomenator 4

8 div. by 4 = 2

20 div. 4 = 5

ans. 2/5
