Question

tìm x 

x : 3\(\dfrac{1}{15}\) - \(\dfrac{3}{4}\) = 2\(\dfrac{1}{4}\)

Answer 1

\(x:\dfrac{46}{15}-\dfrac{3}{4}=\dfrac{9}{4}\\ x:\dfrac{46}{15}=\dfrac{9}{4}+\dfrac{3}{4}\\ x:\dfrac{46}{15}=3\\ x=3.\dfrac{46}{15}\\ x=\dfrac{46}{5}\)

Answer 2

`x : 3 1/15 - 3/4 = 2 1/4`

`=> x : 46/15 - 3/4 = 9/4`

`=>x : 46/15= 9/4 + 3/4`

`=>x : 46/15= 12/4`

`=>x : 46/15=3`

`=> x= 3 xx 46/15`

`=>x= 46/5`

Answer 3

`x : 3 1/15 -3/4 = 2 1/4`

`x: 46/15 - 3/4 = 9/4`

`x:46/15 = 9/4 + 3/4`

`x:46/15 = 12/4`

`x:46/15 = 3`

`x=3 xx 46/15`

`x=46/5`

Vậy `x=46/5`

Answer 4

=>x:\(\dfrac{1}{5}\)-\(\dfrac{3}{4}\)=\(\dfrac{1}{2}\)

=>x=21/20
