REPEATING DECIMALS

|NOTES: |To Convert Repeating Decimals to Fractions: |

| |Let x equal the repeating decimal number. This step creates an equation. |

| |Identify the repeating digit(s) in the decimal number. |

| |Multiply this equation by a power of 10 to move the repeating digits to the left of the decimal point. This step creates a second equation. |

| |Look that the original decimal number (from step 1). If the repeating digits aren’t already immediately to right of the decimal point, multiply the |

| |second equation by another power of 10 to achieve this. This step creates a third equation. |

| |Stack the equations (align the decimal points), and then subtract the left and right sides of the equations. The resulting difference is a new equation. |

| |Subtraction eliminates the repeating digits. |

| |Solve the new equation for x. The result will be a fraction (or ratio of integers). |

| |Simplify the fraction. |

| |Convert the following decimals into fractions. |

|EXAMPLES:|1. |[pic] |2. |[pic] |

| |3. |[pic] |4. |[pic] |

| |5. |[pic] |6. |[pic] |
