Question

a)x + \(\dfrac{3}{7}\) = \(\dfrac{3}{4}\) x \(\dfrac{2}{3}\)

b)\(\dfrac{6}{5}\) : x = 1 : \(\dfrac{5}{2}\)

Giúp mình với mn người ơi

Answer 1

`x + 3/7 = 3/4 xx 2/3`

`x + 3/7 = 1/2`

`x = 1/2 - 3/7`

`x = 7/14 - 6/14`

`x = 1/14`

 

`6/5 : x = 1 : 5/2`

`6/5 : x = 1 xx 2/5`

`6/5 : x = 2/5`

`x = 6/5 : 2/5`

`x = 6/5 xx 5/2`

` x = 3`

Answer 2

a: =>x+3/7=1/2

=>x=1/2-3/7=7/14-6/14=1/14

b: 6/5:x=1x2/5=2/5

=>x=6/5:2/5=3
