Question

Y x 2/3 = 4/5                Y : 3/4 = 5/6

 

Đặt phép tính rõ ràng :

Answer 1

y=6/5

y=5/8

Answer 2

Y x 2/3 = 4/5   

y=4/5 : 2/3

y=  6/5         

Y : 3/4 = 5/6

y= 5/6 x 3/4

y=5/8

Answer 3

a,y.2/3=4/5

  y        =4/5:2/3

  y        =6/5

b,y:3/4=5/6

   y      =5/6.3/4

   y      =5/8

Answer 4

y x 2/3 = 4/5

y = 4/5 : 2/3

y = 6/5

y : 3/4 = 5/6

y = 5/6 x 3/4

y = 15/24

Answer 5

y=6/5

y=5/8
