Question

Tim y A) ( 4 1/5 -y) ×1 1/4 = 9/14+5/7

Answer 1

1\(\dfrac{1}{4}\)hay \(1\dfrac{1}{14}\)

Answer 2

`(4 1/5-y)xx1 1/14=9/14+5/7`

`(21/5-y)xx15/14=19/14`

`21/5-y=19/14:15/14`

`21/5-y=19/15`

`y=21/5-19/15`

`y=44/15`

Answer 3

\(\left(4\dfrac{1}{5}-y\right)\cdot1\dfrac{1}{4}=\dfrac{9}{14}+\dfrac{5}{7}\)

\(\left(\dfrac{21}{5}-y\right)\cdot\dfrac{5}{4}=\dfrac{19}{14}\)

\(\dfrac{21}{5}-y=\dfrac{19}{14}:\dfrac{5}{4}\)

\(\dfrac{21}{5}-y=\dfrac{38}{35}\)

\(y=\dfrac{21}{5}-\dfrac{38}{35}\)

\(y=\dfrac{109}{35}\)
