Question

Tìm y, biết:

y : \(\dfrac{5}{11}\) = \(\dfrac{2}{5}\) : 2

(Các bạn nhớ trình bày đầy đủ nhé!)

Answer 1

`y : 5/11 = 2/5 : 2`

`=> y : 5/11 = 2/5 xx1/2`

`=> y : 5/11 = 2/10`

`=> y : 5/11 =1/5`

`=> y= 1/5 xx 5/11`

`=> y= 5/55`

`=> y=1/11`

Answer 2

\(y:\dfrac{5}{11}=\dfrac{2}{5}:2\)
\(y:\dfrac{5}{11}=\dfrac{2}{5}\times\dfrac{1}{2}\)
\(y:\dfrac{5}{11}=\dfrac{1}{5}\)
\(y=\dfrac{1}{5}\times\dfrac{5}{11}\)
\(y=\dfrac{1}{11}\)
