Convert 0.45 (5 is a repeating number) to a fraction

Jobisdone [24]

Let the given number be 'x',

$\begin{gathered} x=0.4\bar{5} \\ x=0.45555555\ldots\ldots \end{gathered}$

Multiply both sides by 10,

$\begin{gathered} 10x=4.\bar{5} \\ 10x=4.5555555\ldots\ldots \end{gathered}$

Subtract the equations,

$\begin{gathered} 10x-x=4.5555\ldots-0.45555\ldots \\ 9x=4.5+0.0\bar{5}-(0.4+0.0\bar{5}) \\ 9x=4.5+0.0\bar{5}-0.4-0.0\bar{5} \\ 9x=4.1 \\ 9x=\frac{41}{10} \\ x=\frac{41}{90} \end{gathered}$

Thus, the recurring decimal number is equivalent to the fraction,

$0.4\bar{5}=\frac{41}{90}$

x=6

Step-by-step explanation:

First, we combine like terms.

6x=2x+24

6x-2x=24
