Step-via-Step Conversion of one.33333333333 to a Fraction

Identifying the Repeating Part

In 1.33333333333, the repeating element is ‘three’. This is important for putting in our equation correctly.

Setting Up the Equation

Let 

𝑥

=

1.33333333333

x=1.33333333333. To dispose of the repeating element, multiply both sides via 10 (due to the fact that one digit repeats):

10

𝑥

=

13.33333333333

10x=13.33333333333

Solving the Equation

Now, subtract the unique equation from this new equation:
