Question

$0.6666 \: in \: \: p \div q \: \: format \:$
​

Answer 1

Answer:

let , x = 0.66666.... i

multiply both sides by 10

then,

10x = 6. 6666...

=> 10x - 6 = 0.6666..

=> 10 x - 6 = x. (using i)

=> 10x - x = 6

=> 9x = 6

$= > x = \frac{6}{9} = \frac{2}{3} . \\ so \: 0.6666 = \frac{2}{3}$
