99X=63

X=63/99

X=21/33=P/Q

Answer 2

The required form is $0.\overline{63}=\frac{7}{11}$

Prime factor of q is 1 and 11 as it is a prime number.

Step-by-step explanation:

Given : Expression 0.63(bar on 63).

To find : Express expression in p/q form and prime factors of q​ ?

Solution :

Let $x=0.\overline{63}$

$x=0.636363...$  ......(1)

Multiply both side by 100,

$100x=63.636363...$  .....(2)

Subtract (1) from (2),

$100x-x=(63.636363...)-(0.636363...)$

$99x=63$

$x=\frac{63}{99}$

$x=\frac{7}{11}$

Here, p=7 and q=11

Prime factor of q is 1 and 11 as it is a prime number.

Therefore, $0.\overline{63}=\frac{7}{11}$
