Выполните действия (а)1 7/9: 2 2/3 (б)3 3/5: 2 1/100 (в)3 3/8: 1/8-1 5/14*7 срочьно

А) 1 7/9 : 2 2/3 = 16/9 : 8/3 = 16/9 * 3/8 = 2/3
б) 3 3/5 : 2 1/100 = 18/5 : 201/100 = 18/5 * 100/201 = 120/67 = 1 53/67
в) 3 3/8 : 1/8 - 1 5/14 * 7 = 17 1/2
1) 3 3/8 : 1/8 = 27/8 * 8/1 = 27
2) 1 5/14 * 7 = 19/14 * 7 = 19/2 = 9 1/2
3) 27 - 9 1/2 = 26 2/2 - 9 1/2 = 17 1/2
