Ответ:
1 1/2
Пошаговое объяснение:
1) 1 1/2 * 2 2/5 = 3/2 * 12/5 = 3/1 * 6/5 = 18/5 = 3 3/5
2) 7 - 3 3/5 = 6 5/5 - 3 3/5 = 3 2/5
3) 3 2/5 : 2 4/15 = 17/5 : 34/15 = 17/5 * 15/34 = 1/1 * 3/2 = 3/2 = 1 1/2
(7 - 1 1/2 * 2 2/5) : 2 4/15 = 1,5
1) 1 1/2 * 2 2/5 = 1,5 * 2,4 = 3,6
2) 7 - 3,6 = 3,4
3) 3,4 : 2 4/15 = 3 4/10 : 2 4/15 = 34/10 : 34/15 = 14/10 * 15/34 = 15/10 = 1,5

(7 - 1 1/2 * 2 2/5) : 2 4/15 = 1,5
1) 1 1/2 * 2 2/5 = 1,5 * 2,4 = 3,6
2) 7 - 3,6 = 3,4
3) 3,4 : 2 4/15 = 3 4/10 : 2 4/15 = 34/10 : 34/15 = 14/10 * 15/34 = 15/10 = 1,5
