Answer 1

Answer:

1. 127/ 24

2. -3/8

Step-by-step explanation:

2 1/8 + 3 1/6

= 17/8  +   19/6

LCM for (6 & 8) = 24

17 x 3   +   19 x 4

8  x 3         6 x 4

= 51 + 76  = 127

       24         24

2. 7/8   -  5/4

   LCM of (8 and 4) = 8

7 x 1     -     5 x 2

8 x 1           4 x 2

7  -  10  =  -3

   8            8
