Answer 1

Ответ:

(3 11/27 - 2 17/18) / 1 23/27 + 3 3/5 / 3 = 1 9/20;

1). 3 11/27 - 2 17/18 = 92/27 - 53/18 = 184/54 - 159/54 = (184 - 159)/54 = 25/54;

2). 25/54 / 1 23/27 = 25/54 / 50/27 = 25/54 * 27/50 = 25 * 27/54 * 50 = 1 * 1/2 * 2 = 1/4;

3). 3 3/5 / 3 = 18/5 / 3 = 18/5 * 1/3 = 18 * 1/5 * 3 = 6 * 1/5 * 1 = 6/5 = 1 1/5;

4). 1/4 + 1 1/5 = 1/4 + 6/5 = 5/20 + 24/20 = (5 + 24)/20 = 29/20 = 1 9/20;
