Key Concepts
To convert a mixed repeating decimal (where some digits after the decimal point do not repeat) to a fraction using the algebraic method: 1. Set an equation where $x$ equals the original decimal. 2. Multiply both sides by a power of $10$ to move the decimal point just before the repeating part. 3. Multiply the original equation by a higher power of $10$ to move the decimal point just after the first repeating block. 4. Subtract the first new equation from the second to eliminate the repeating decimal part. 5. Solve for $x$ and simplify the resulting fraction.
