Answer 1

3/4-8 1/4=-8+3/4-1/4=-8+3/4-1/4=-8+2/4=-15/2=-7 1/2
-4 2/3+5=1/3
-7 1/2:3 1/2=-15/2:7/2=-15/2*2/7=-15/7
1/3:10=1/30
-15/7:1/30=-15/7*30/1=-450/7=-64 2/7
-1 7/8+3 1/8=2+1/8-7/8=2+(-6/8)=10/8=1 1/4
1 1/4*1 3/5=5/4*8/5=8/4=2
-1 3/8+2=5/8
5/8:3 1/8=5/8*8/25=1/5
2:1/5=10
-64 2/7-10=- 74 2/7

Answer 2

(((3/4 - 35/4)/(7/2))(-14/3+15/3)/10)-------((-15/8+25/8)*8/5)/(-11/8+16/8)/(25/8)
= ((-32/4*2/7)/(1/3*1/10))-(10/8*8/5)/(5/8*8/25)
= ((-32/14)/(1/30))-(2/(1/5))
=(-960/14)-10
=(-960/14)-(140/14)
=-1100/14
