Question

(3 целых 3/11*1 целая 2/9-2 целых 3/8)*16/39 ПЛИЗ

---

Answer 1

(3 3/11 * 1 2/9 - 2 3/8) * 16/39 = 2/3,

1) 3 3/11 * 1 2/9 = 36/11 * 11/9 = 36/9 = 4,
2) 4 - 2 3/8 = 3 8/8 - 2 3/8 = 1 5/8,
3) 1 5/8 * 16/39 = 13/8 * 16/39 = 2/3

Answer 2

(3/11×2/3-3/4)×16/39
(1/11×2-3/4)×16/39
(2/11-3/4)×16/39
(-25/44)×16/39
-25/11×4/39
-100/429
