First make them improper fractions:
5 3/7 = 38/7
4 1/2 = 9/2
Then you have to find a common denominator (14)
Whatever you times the bottom by (to get the common denominator) do the same to top
38 X 2 and 7 X 2 = 76/14
9 X 7 and 2 X 7 = 63/14
Now add the top numbers (76 + 63) = 139
Answer 139/14 or 9 13/14

add together the two whole numbers and then find the LCD for the two fractions and add those two together!
soo...
4+5=9
3/7+1/2=?
3/7x2 and 1/2x7
6/14+7/14=13/14
9+13/14=9 13/14
