Converting a Repeating Decimal into a Fraction:

Scenario 1:

When the series of repeating digits begins immediately after the decimal point.

- Write the repeating part of the number in the numerator of a fraction
- Write the denominator of the fraction as the same number of 9's as we have digits in the numerator
- Simplify the fraction

Scenario 2:

When the series of repeating digits does not begin immediately after the decimal point.

- Set the repeating decimal equal to a variable
- We will refer to this as equation #1

- Multiply both sides of the equation by 10
^{n}where n is the number of digits in the repeating pattern- We will refer to this as equation #2

- Subtract away equation #1 from equation #2
- We do this by subtracting the left side of equation #1 away from the left side of equation #2 and the right side of equation #1 from the right side of equation #2

- Solve the equation, this will give us the fractional equivalent for our repeating decimal
- Simplify the fraction
