Answer 2

Concept

A bar over the number in a decimal number indicates that the number is repeating indefinitely. Such numbers are called repeating or recurring decimal numbers.

Given

an equation

10x = 0.3bar - 0.2bar

Find

we need to find the value of x as given in the above equation

Solution

We have 10x = 0.3bar - 0.2bar

Here, 0.3bar = 0.333..

and 0.2bar = 0.222...

Thus, the equation can be written as

10x = 0.333... - 0.222...

10x = 0.111

or 10x = 0.1bar

x = (0.111...)/10

x = 0.0111...

or x = 0.01bar

Thus, the value of x in the given expression is 0.0111... or 0.01bar.
