Answer 3

а) 1/2 * 3/5 = 3/10 4 * 3/5 = 12/5 1/2 : 3/5 = 5/6 4 : 3/5 = 20/3 3/5 : 4 = 3/20

б) 4/7 * 1/3 = 4/21 4/7 * 5 = 20/7 4/7 * 5 = 20/7 4/7 : 1/3 = 12/7 4/7 : 5 = 4/35 5 : 4/7 = 35/4

в) 2/5 * 3/7 = 6/35 2 * 3/7 = 6/7 2/5 : 3/7 = 14/15 2 : 3/7 = 14/3 3/7 : 2 = 3/14

г) 3/4 * 1/5 = 3/20 3/4 * 7 = 21/4 3/4 : 1/5 = 15/4 3/4 : 7 = 3/28 7 : 3/4 = 28/3
