Question

(-3целых 1/3 х 1,9 + 19,5: 4 целых1/3) : (0,16- 62/75.

---

Answer 1

1) - 3 1/3 * 1,9 = - ( 10/3 ) * ( 19/10 ) = - 19/3 = - 6 1/3 
2) 19,5 : 4 1/3 = 195/10 : 13/3 = 39/2 : 13/3 = 9/2 = 4 1/2
3) - 6 1/3 + 4 1/2 = - 5 8/6 + 4 3/6 = - 1 5/6 
4) 0,16 - 62/75 = 4/25 - 62/75 = 12/75 - 62/75 = - 50/75 = - 2/3 
5) - 1 5/6 : ( - 2/3 ) = - ( 11/6 ) : - ( 2/3 ) = 11/4 = 2,75 
Ответ 2,75
