1. 16/81 × 45/57 × 19/42. 72/49 × 5/88 × 77/253. 18/95 × 35/3 × 19/424. 20/23 × 73/48 × 46/73Решите, пожалуйста

Answer 1

1) 16/81 * 45/57 * 19/4 = 4/9 * 5/3 * 1/1 = 20/27
2) 72/49 * 5/88 * 77/25 = 9/7 * 1/1 * 1/5 = 9/35
3) 18/95 * 35/3 * 19/42 = 6/5 * 5/1 * 1/6 сокращаешь и получится 1
4) 20/23 * 73/48 * 46/73 = 5/1 * 1/1 * 1/1 = 5
