Answer 2

QUESTION :-

Convert 0.7777... into p/q Form :-

SOLUTION :-

Let x = 0.77777.....       …(i)

Since the Repeating Block of Digits is 1, we multiply x by 10

∴ 10x = 7.77777.....      …(ii)

Subtracting (i) from (ii), we get -

$\Rightarrow 10x = 7.77777.....\:- x = 0.77777.....\\\\\Rightarrow \bold {9x = 7.00000.....}$

=> 9x = 7

∴ x = $\bold {\frac{7}{9}}$

COCLUSION :-

0.77777..., when Converted into p/q Form, gives 7/9
