Express each of the following decimals in the form $\frac{p}{q}$:$ 0 . \overline{4} $
Given:
The given decimal number is \( 0 . \overline{4} \).
To do:
We have to express the given decimal in $\frac{p}{q}$ form.
Solution:
$0. \overline{4}$
Let $x = 0.4444....$
Multiply both sides by 10.
$10x = 10(0.4444....)$
$10x = 4.4444.....$
Therefore,
$10x-x = 4.4444.... - 0.4444.....$
$9x = 4$
$x = \frac{4}{9}$
Therefore,
$0. \overline{4}$ in $\frac{p}{q}$ form is $\frac{4}{9}$.
