Question 278996
3 3/4 + 3 5/6 

First change the mixed fractions to improper fractions:

3 3/4 = 15/4

3 5/6 = 23/6

To add these two improper fractions we need a common denominator. The smallest common denominator is 12 so we need to convert each from fourths and sixths to twelths:

15/4 = (15*3)/(4*3) = 45/12

26/6 = (26*2)/(6*2) = 52/12 

Now we can add these:

45/12 + 52/12 = 97/12 = 8 1/12
