Answer 1

A) 3/2 + 7/2 + 9/2

(3 + 7 + 9)/2 = 19/2

B)4/5 + 12/5 - 8/5

(4+12- 8 )/5= 8/5

C) 1/2 + 1/4 + 1/8

(4 + 2 + 4)/8

=7/8

d) 9/2 - 4/3 + 5/6 - 3/8

(108 - 32 + 20 - 9)/24

87/24

= 29 /8

E)10/9 + 10/4- 4/3-1/2

10/9 +5/2 - 4/3 -1/2

10/9 + (5 - 1)/2 -4/3

10/9 + 4/2 - 4/3

10/9 + 2- 4/3 = (10+18-19)/9=16/9
