4/6 = 2/3           2/4 = 1/2            5/7 = 5/7             3/3 = 1            3/9 = 1/3            4/8 = 1/2
 
 

Fill in the blank spaces in the following addition problems involving fractions.  (You may leave your answer as an improper fraction, but please simplify your answer into lowest terms.)

1/3 + 1/3 = 2/3              2/8 + 3/8 = 5/8                       1/2 + 1/3 = 5/6                    1/10 + 3/10 = 2/5

1/4 + 1/3 = 7/12             4/6 + 2/3 = 4/3 or 1 1/3            2/7 + 4/5 = 38/35                3/4 + 7/8 = 13/8

4/9 + 7/8 = 95/72 or 1 23/72      2/5 + 2/3 = 16/15 or 1 1/15            2/3 + 4/3 = 6/3 or 2

1/7 + 1/8 = 15/56           2/2 + 1/4 = 5/4 or 1 1/4           3/10 + 3/5 = 9/10

1/2 + 2/3 = 7/6 or 1 1/6

Extra credit: (Fill in the blanks.)

2/4 + 3/4 = 5/4        1/7 + 1/2 = 9/14        1/3 + 3/4 = 13/12       5/5 + 2/5 = 7/5

3/4 - 1/4 = 2/4 or 1/2       4/5 - 1/5 = 3/5       5/4 + 2/7 = 43/28 or 1 15/28
