А) 2/3:0,2 = 2/3 : 2/10 = 2/3 * 10/2 = 10/3 = 3 1/3
б) 1,4:2/7 = 14/10 * 7/2 = 7/5 * 7/2 = 49/10 = 4,9
в) 8/9:1,6 = 8/9:16/10 = 8/9 * 10/16 = 8/9 * 5/8 = 5/9
г) 5/6:1,5 = 5/6:15/10 = 5/6 * 10/15 = 5/6 * 2/3 = 5/9
д) 0,8:4/7 = 4/5 * 7/4 = 7/5 = 1,4
е) 5/12:0,01 = 5/12:1/100 = 5/12 * 100 = 500/12 = 41 2/3
