Answer 2

$\displaystyle \bf{ 0. \overline{63} = \frac{7}{11} }$

Which is of the form p/q where p , q are integers and q ≠ 0

Given :

The number $\displaystyle \sf{ 0. \overline{63} }$

To find :

To express in the form p/q where p , q are integers and q ≠ 0

Solution :

Step 1 of 2 :

Write down the given number

The given number is $\displaystyle \sf{ 0. \overline{63} }$

Step 2 of 2 :

Express in the form p/q where p , q are integers and q ≠ 0

$\displaystyle \sf{ Let \: \: x = 0. \overline{63} }$

Then x = 0.636363... - - - - - - - (1)

Multiplying both sides by 100 we get

100x = 63.636363... - - - - - - (2)

Equation 2 - Equation 1 gives

99x = 63

$\displaystyle \sf{ \implies x = \frac{63}{99} }$

$\displaystyle \sf{ \implies x = \frac{7 }{11} }$

$\displaystyle \sf{ \therefore \: \: 0. \overline{63} = \frac{7}{11}}$

Which is of the form p/q where p , q are integers and q ≠ 0
