Answer 2

Correct Question :

• Express $\rm{0.7.......}$ in $\rm{\dfrac{p}{q}}$ form

________________________________________________

Let x = $\rm{0.7777...}$          ---- [1]

• Multiply 10 to Both Sides of the Equation

$\longrightarrow$ 10x = $\rm{7.777...}$          ---- [2]

• Subtract Equation [1] from Equation [2]

$\longrightarrow$ 10x - x = $\rm{7.777-0.777}$

$\longrightarrow$ 9x = $\rm{7}$

• Dividing Both Sides by 9

$\longrightarrow$ x = $\rm{\dfrac{7}{9}}$
