4)1:3/10=
5)7/15:14=
6)1 целая 1/9: 5/6=
7)1 целая 4/15: 7 целых 3/5=
8)3 целых 4/7: 1 целая 4/21:3

Answer 1

1) 5/7 : 5/4 = 5/7 * 4/5 = 4/7
2) 1/8 : 1/88 = 1/8 * 88/1 = 11
3) 7/8 : 21/56 = 7/8 * 56/21 = 7/3 = 2 1/3
4) 1 : 3/10 = 1 * 10/3 = 10/3 = 3 1/3
5) 7/15 : 14 = 7/15 * 1/14 = 1/30
6) 1 1/9 : 5/6 = 10/9 : 5/6 = 10/9 * 6/5 = 4/3
7) 1 4/15 : 7 3/5 = 19/4 : 38/5 = 19/4 * 5/38 = 5/8
8) 3 4/7 : 1 4/21 : 3 = 25/4 : 25/21 : 3 = 25/4 * 21/25 * 1/3 = 7/4 = 1 3/4
