Question

1) 5 2/9-2 2/3x=4 5/6; 2) (x-5 1/3):1 4/11=9 1/6​

Answer 1

Пошаговое объяснение:

1)

5 2/9 - 2 2/3х = 4 5/6

2 2/3х = 5 2/9 - 4 5/6

2 2/3х = 5 4/18 - 4 15/18

2 2/3х = 4 22/18 - 4 15/18

8/3х = 7/18

х = 7/18 : 8/3

х = 7/18 * 3/8

х = 7/6 * 1/8

х = 7/48

2)

(х - 5 1/3) : 1 4/11 = 9 1/6

х - 5 1/3 = 9 1/6 * 1 4/11

х - 5 1/3 = 55/6 * 15/11

х - 5 1/3 = 5/2 * 5/1

х - 5 1/3 = 25/2

х - 5 1/3 = 12 1/2

х = 12 1/2 + 5 1/3

х = 12 3/6 + 5 2/6

х = 17 5/6
