Question

Уравнения : 1) х * (1 целых 2/3 + 5/9) = 2/3
2) х : ( 4 целых 1/3 - 3) = 1 целых 1/2

Answer 1

Х • ( 1 2/3 + 5/9 ) = 2/3
1 2/3 + 5/9 = 1 6/9 + 5/9 = 1 11/9 = 2 2/9 = 20/9
Х • 20/9 = 2/3
Х = 2/3 : 20/9
Х = 3/10
Ответ 3/10 ( или 0,3 )
---------
Х : ( 4 1/3 - 3 ) = 1 1/2
Х : ( 1 1/3 ) = 1 1/2
Х : ( 4/3 ) = 3/2
Х = 4/3 • 3/2
Х = 2
