Answer 1

A)

3/13 + 5/13 = 8/13

B)

2/9 + 6/9 = 8/9

C)

5/16 + 361/1 --> mmc : 16

= 5/16 + 5056/16

= 5061/16


D)

6/7 - 2/7 = 4/7

E)

11/15 - 2/15 = 9/15 = 3/5


F)

1/3 + 1/4 --> mmc:12

4/12+ 3/12

= 7/12


G)

1/3 + 2/4 --> mmc:12

4/12 + 6/12 = 10/12 = 5/6


H)

9/10 - 7/20 ---> mmc:20

18/20 - 7/20 = 11/20


I)

11/18 - 5/12 ---> mmc:36

22/36 - 15/36 = 7/36



J)

4/21 + 1/4 ---> mmc:84

16/84 + 21/84 = 37/84
