Question

Как решить (2 5/6-3 4/5*1 1/9):(-3,75)

Answer 1

1) 3 4/5 • 1 1/9 = 19/5 • 10/9 = 38/9 = 4 2/9
2) 2 5/6 - 4 2/9 = 2 15/18 - 4 4/18 = 2 15/18 - 3 22/18 = - 1 7/18
3) - 1 7/18 : ( - 3,75 ) = 25/18 : 15/4 = 20/54 = 10/27
Ответ 10/27

Answer 2

(2 5/6 - 3 4/5 * 1 1/9) : (-3,75) = 10/27,

1) 3 4/5 * 1 1/9 = 19/5 * 10/9 = 38/9 = 4 2/9,
2) 2 5/6 - 4 2/9 = 17/6 - 38/9 = 51/18 - 76/18 = -25/18,
3) -25/18 : (-3,75) = 25/18 : 375/100 = 25/18 * 100/375 = 10/27
