Answer 1

3/4*8= 24/4 = 6

1:4/5= 1 * 5/4 = 5/4 = 1 1/4

2/3*3/4=skracamy = 1/1*1/2 = 1/2

5/8:1=5/8 * 1 = 5/8

1 1/2*4/5=3/2 * 4/5 = skracamy= 3/1*2/5 = 6/5 = 1 1/5

1/2:3/4=1/2 * 4/3 = skaracamy = 1/1 * 2/3 = 2/3

2 1/4*5/6*1 3/5=9/4 * 5/6 * 8/5 = 360/120 = skracamy przez 120=  3/1 = 3

1 1/3:1 1/2= 4/3 * 2/3 = 8/9
