Question

[Nguyễn Thị Thùy Trang 1]

\(\frac{5}{6}\): ( Y + \(\frac{7}{9}\)) = \(\frac{3}{4}\)

13, 104 : y - 8,72 = 6,88

Answer 1

[Nguyễn Văn Khởi]

a)5/6:(y+7/9)=3/4

     (y+7/9)=5/6:3/4

     Y+7/9=10/9

     y       =10/9-7/9

    y        =1/3    

b)13.104:y-8.72=6.88

   13.104:y       =6.88+8.72

   13.104:y       =15.6

              y       =13.104:15.6

              y       =0.84
