Answer 1

3/2-(-5/4)+(-7/5)-(-41/40)=60/40+50/40-56/40+41/40=95/40=19/8

(-2/3)+(-3/4)-1/5-(-1)=-40/60-45/60-12/60+60/60=-37/60

(1/2-3/4)-(5/2-5/4)-(3/2-3/4)=(2/4-3/4)-(10/4-5/4)-(6/4-3/4)=-1/4-5/4-3/4=-9/4

(-2/3+4/5+1)-(-4/3+2/5-2)+(-2+5/3)=(-10/15+12/15+15/15)-(-16/15+6/15-30/15)+(-6/3+5/3)=17/15+40/15-1/3=57/15-5/15=52/15

(1-3/4+2/3)-)1-5/3+1/4)-(1-4/3-3/4)=(12/12-9/12+8/12)-(12/12-20/12+3/12)-(12/12-16/12-9/12)=11/12+5/12-13/12=3/12=1/4

0,8x(0,75-1/4)x(-2)=8/10x(75/100-1/4)x(-2)=4/5x(3/4-1/4)x(-2)=4/5x2/4x(-2)=-4/5

(-4)x(-8/3)x(-3/8-3/8x5/3)=(-4)x(-8/3)x(-3/8-15/24)=(-4)x(-8/3)x(-9/24-15/24)=(-4)x(-8/3)x(-24/24)=(-4)x(-8/3)x(-1)=-32/3

(1/2-1/3)x(1/2+1/3)x(-1)=(3/6-2/6)x(3/6+2/6)x(-1)=1/6x5/6x(-1)=-5/36

-1/2-[-1/5+(2-1/3)]=-15/30-[-6/30+60/30-10/30]=-15/30-44/30=-59/30

0,1-[3/2-(0,5+0,4)]=0,1-[1,5-0,9]=0,1-0,6=-0,5

(-2/3)x(6/5)+1/2x(-4/3)-(-2)x3/10=(-2/3)x(6/5)+1/2x(-4/3)-(-2)x3/10=-12/15-4/6+6/10=-24/30-20/30+18/30=-26/30=-13/15

1/2-(1/3+1/4-1/5)=30/60-(20/60+15/60-12/60)=30/60-23/60=7/60

2/3-(5/2-5/4)=2/3-(10/4-5/4)=2/3-5/4=8/12-15/12=-7/12
