Answer 1

1) -5+ 7/5 = (-25+7)/5 = -18/5
-18/5 × 1/4 = -18/20 = -9/10

2) -1 +3/2 = (-2+3)/2 = 1/2
5/2 + 1/6 = (15+1)/6 = 16/6 = 8/3
1/2 × 8/3 = 8/6 = 4/3

3) (-12+5+4)/12 = -1/4
-1/4× -12=3

4) 6/7

5)5/3 +1/3 -7/8 = (40+8-21)/8 = 9/8

6)5/3 -1 = (5-3)/3 = 2/3
7/2 -2 = (7-4)/2 = 3/2

2/3 × 3/2 = 1
