Question

Answer 1

`x - 3/4 = 1/2`

`x = 1/2 + 3/4`

`x = 5/4`

____________

`x : 1/4 = 8`

`x = 8 xx 1/4`

`x = 8/4`

`x = 2`

Answer 2

\(a.x-\dfrac{3}{4}=\dfrac{1}{2}\)

\(x=\dfrac{1}{2}+\dfrac{3}{4}\)

\(x=\dfrac{5}{4}\)

\(b.x:\dfrac{1}{4}=8\)

\(x=8\times\dfrac{1}{4}\)

\(x=2\)

Answer 3

a. x − \(\dfrac{3}{4}\) = \(\dfrac{1}{2}\)

    x = \(\dfrac{1}{2}\) + \(\dfrac{3}{4}\)

    x = \(\dfrac{5}{4}\)

 

b. x : \(\dfrac{1}{4}\) = 8

    x = 8 x \(\dfrac{1}{4}\)

    x = \(\dfrac{8}{4}\)  = 2
