5/14+18/35+( одна целая 1/4-5/14): (5/12)в квадрате . ! )

5/14 + 18/35 + (1 целая 1/4 - 5/14) : (5/12)в квадрате = 6 целых 1/70

1) 1 целая 1/4 - 5/14 = 5/4 - 5/14 = 35/28 - 10/28 = 25/28
2) (5/12)в квадрате = 5/12 * 5/12 = 25/144
3) 25/28 : 25/144 = 25/28 * 144/25 = 144/28 = 5 4/28 = 5 целых 1/7
4) 5/14 + 18/35 = 25/70 + 36/70 = 61/70
5) 5 целых 1/7 + 61/70 = 5 целых 10/70 + 61/70 = 5 целых 71/70 = 6 целых 1/70
