(Двумя пробелами отделены целые)

Answer 1

7/8 : 2 = 7/8 * (умножить) 1/2= 7/16
3/8 : 3 = 3/8 * 1/3 = 3/24 = 1/8
5 : 2/5 = 5 * 5/2 =25/2 = 12 1/2
8 : 4/5 = 8 * 5/4 = 40/4 = 10
3/7 ; 1/2 = 3/7 * 2/1 = 6/7
3 1/2 : 2/3 = 7/2 * 3/2 = 21/4= 5 1/4
41/2 : 11/2 = 41/2 * 2/11 = 82/22 = 41/11 = 3 8/11
11/2 : 11/10 = 11/2 *10/11 = 1/2 * 1/10 = 1/20
10 1/3 : 2 2/3 = 31/3 * 3/8 = 93/24 = 3 21/24 = 3 7/8
4/15 : 3 1/15 = 4/15 : 46/15 = 4/15 * 15/46 = 4 * 1/46 = 4/46= 2/23
