Помогите решить примеры по действиям
a) = 28/9 : 7/6 = 28/9 * 6/7 = 8/3 = 2 2/3
б) = 23/20 : 46/10 = 23/20 * 10/46 = 1/4
в) = 24/7 : (1 : 7/6) - 2 7/9 = 24/7 : (1 * 6/7) - 2 7/9 = 24/7 * 7/6 - 2 7/9 = 4 - 2 7/9 = 1 2/9
1) 3 1/9 : 1 1/6= 28/9 : 7/6= 28/9 * 6/7=24/9=8/3=2 2/3 2) 1 3/20 : 4,6= 23/20 : 46/10=23/20*10/46=1/4=0.25 3) 3 3/7 : (1:1 1/6)-2 7/9= 3 3/7:6/7-2 7/9=24/7:7/6=4-2 7/9=1 2/9
