-1 1/16
Пошаговое объяснение:
1 3 2 9 4 5 8 6 7
(0,71-1/4) : (0,71+1/4) * ((-15+9 1/3) : 2 5/9)) : ((-(-19 2/3 + 11 7/9) * 9/71)) = -1 1/16
По действиям:
1. 0,71 - 1/4 = 71/100 - 1/4 = 71/100 - 25/100 = 46/100 = 23/50
2. 0,71 + 1/4 = 71/100 + 1/4 = 71/100 + 25/100 = 96/100 = 48/50
3. 23/50 : 48/50 = 23/50 * 50/48 = 23/48
4. -15 + 9 1/3 = -5 2/3
5. -5 2/3 : 2 5/9 = -17/3 * 9/23 = -51/23
6. -(-19 2/3) + 11 7/9 = -(-177/9 + 106/9) = - (-71/9) = 71/9
7. 71/9 * 9/71 = 1
8. -51/23 : 1 = -51/23
9. 23/48 * (-51/23) = -51/48 = -17/16 = -1 1/16
