Answer 1

a) (-3,2)*(-2)*(-5)=(-32/10)*(-2)*(-5)=-32

b) (-4 1/2)*10*3=(-9/2)*10*3=-9*5*3=-135

c) 15*2,5*8=15*25/10*8=3*25*4=300

d) 3 3/4*5 1/5*(-100)=15/4*26/5*(-100)=3*26*(-25)=-1950

e) 1 1/4*52*(-3 1/13)=5/4*52*(-40/13)=5*(-40)=-200

f) 8 1/3*(-6 1/5)*(-15/16)=25/3*(-31/5)*(-15/16)=5*(-31)*(-5/16)=-155*(-5/16)=775/16=48 7/16

g) (-0,2)*(-0,1)*(-3,5)=(-2/10)*(-1/10)*(-35/10)=(-1/5)*(-1/2)*(-7/10)=-7/100

h) 15*(-3/5)*4 2/7=15*(-3/5)*30/7=-9*30/7=-270/7=-38 4/7

Answer 2

a) (-3,2)*(-2)*(-5)= (-32/10)*10 = - 320/10 = -32

b) (-4 1/2)* 10*3= -9/2*30= -270/2 = -135

c)15*(2,5)*8= 120*25/10=300

d)3 3/4*(5 1/5)*(-100)=15/4*26/5*(-100)=78/4*(-100)= - 7800/4 = - 1950

e)1 1/4*52*(-3 1/13)= 5/4*52*(- 40/13) = 65*(-40/13)= skaracamy=5*(-40/1) = - 200

f) 8 1/3*(-6 1/5)*(-15/16)= 25/3*(-31/5)*(-15/16) =skaracamy= 5/1*(-31)*(-5/16)=775/16= 48  7/16

g) (-0,2)*(-0,1)*(-3,5)=(-2/10)*(-1/10)*(-35/10)=skaracamy=(-1/10)*(-1/1)*(-7/10)= - 7/100= - 0,07

h) 15*(-3/5)*4 2/7=15* (-3/5)*30/7 = skaracamy=3*(-3)*30/7= - 270/7  = - 38 4/7
