Пошаговое объяснение:
1 53/72
Пошаговое объяснение:
3 1/8 : ((4 5/12 - 3 13/24) * 4/7 + ( 3 1/18 - 2 7/12) * 1 10/17) = 1 53/72
6 1 2 5 3 4
1. 4 5/12 - 3 13/24 = 53/12 - 85/24= 21/24
2. 21/24 * 4/7 = 1/2
3. 3 1/18 - 2 7/12 = 55/18 - 4/7 = 17/36
4. 17/36 * 1 10/17 = 17/36 * 27/10 = 459/360 = 1 11/40
5. 1/2 + 1 11/40 = 1/2 +51/40 = 72/40 = 1 4/5
6. 3 1/8 : 1 4/5 = 25/8 : 9/5 = 125/72 = 1 53/72
