Szczegółowe wyjaśnienie:
-8/9:(-16/27)= -8/9*(-27/16)=3/2=1 1/2
-1 5/9:7/9= -14/9 *9/7= -2
7:(-5/6)=7*(-6/5)= -42/5= -8 2/5
-5/9:(-7/19)= -5/9*(-19/7)=95/63=1 32/63
2 3/4:(-3 1/7)=11/4: (-22/7)=11/4*(-7/22)=-7/4= -1 3/4
7 1/2:(1 7/8)=15/2 :15/8=15/2*8/15=8/2=4
-3 5/7:(-3,25)= -26/7: (-3 1/4)=-26/7 :(-13/4)= -26/7*(-4/13)=8/7=1 1/7
-1,5:3/4= -3/2: 3/4=-3/2*4/3= -2
-4,8:1 1/8= -24/5 :9/8=-24/5*8/9= -64/15= -4 4/15
-2 3/4:1,1= -11/4 :11/10= -11/4*10/11= -10/4= -5/2= -2 1/2
-1,6:(-2/15)= -16/10 :(-2/15)=-16/10*(-15/2)=24/2=12
13,2:(-0,9)= 132/10 :(-9/10)=132/10*(-10/9)= -132/9= -14 6/9=-14 2/3
-2/5:2,5= -2/5: 5/2= -2/5*2/5=-4/25
-3 5/7:3,25= -26/7 :3 1/4=-26/7:13/4= -26/7*4/13= -8/7= -1 1/7
