1) 2/3
2) 5/8
3) 2/3
4) 2/3
5) 1 2/3
6) 1 1/2
Пошаговое объяснение:
1) 1/2 : 3/4 = 1/2 * 4/3 = 2/3
2) 5/12 : 2/3 = 5/12 * 3/2 = 5/8
3) 4/9 : 2/3 = 4/9 * 3/2 = 2/3
4) 8/15 : 4/5 = 8/15 * 5/4 = 2/3
5) 2/5 : 6/25 = 2/5 * 25/6 = 5/3 = 1 2/3
6) 3/8 : 1/4 = 3/8 * 4/1 = 3/2 = 1 1/2
1 1/2:3/4=1/2*3/4=3/8
2 5/12:2/3=5/12*3/2=15/24=5/8
3 4/9:2/3=4/9*3/2=12/18=2/3
4 8/15:4/5=8/15*5/4=40/60=2/3
5 2/5:6/25=2/5*25/6=50/30=5/3=1 целая 2/3
6 3/8:1/4=3/8*4/1=12/8=1 целая 1/2
