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
