Giải đầy đủ giúp mik nhé

Answer 1

y : 1/4 = 1 - 3/7

y : 1/4 = 4/7 

y = 4/7  x 1/4

y = 1/7

Answer 2

y : 1/4 = 4/7

y = 4/7 x 1/4

y = 1/7

Answer 3

y=1/7

Answer 4

\(y:\dfrac{1}{4}=\dfrac{1}{1}-\dfrac{3}{7}\)

\(y:\dfrac{1}{4}=\dfrac{7-3}{7}=\dfrac{4}{7}\)

\(y=\dfrac{4}{7}.\dfrac{1}{4}\)

\(y=\dfrac{4}{7}\)

 

Answer 5

\(y\div\dfrac{1}{4}=1-\dfrac{3}{7}\)

\(y\div\dfrac{1}{4}=\dfrac{4}{7}\)

\(y=\dfrac{4}{7}\cdot\dfrac{1}{4}\)

\(y=\dfrac{1}{7}\)

Answer 6

y : 1/4 = 4/7

y = 4/7 x 1/4

y = 1/7

Answer 7

y:1/4=1-1/7

y   =4/7-1/4

y   =1/7

Answer 8

\(y\div\dfrac{1}{4}=1-\dfrac{3}{7}\) 

\(y\div\dfrac{1}{4}=\dfrac{4}{7}\) 

       \(y=\dfrac{4}{7}\times\dfrac{1}{4}\)

      \(y=\dfrac{1}{7}\)

Answer 9

1/7
