How to convert a repeating decimal to a fraction?
Condition 1: Single repeating digit (e.g., 0.333…)
- Identify the repeating digit(s) and assign it to a variable (e.g., x).
- Set up an equation where x represents the repeating part: x = 0.333…
- Multiply both sides of the equation by a power of 10 that matches the number of decimal places in the repeating part. In this case, we multiply by 10 because there is one repeating digit after the decimal point: 10x = 3.333…
- Subtract the original equation from the multiplied equation: 10x - x = 3.333… - 0.333…
- Simplifying the right side gives: 9x = 3
- Solve for x by dividing both sides of the equation by 9: x = 3/9
- Simplify the fraction if possible: x = 1/3
Condition 2: Repeating block of digits (e.g., 0.126126126…)
- Identify the repeating block of digits and assign it to a variable (e.g., x).
- Set up an equation where x represents the repeating block: x = 0.126126126…
- Multiply both sides of the equation by a power of 10 that matches the number of decimal places in the repeating block. In this case, we multiply by 1000 because there are three repeating digits after the decimal point: 1000x = 126.126126…
- Subtract the original equation from the multiplied equation: 1000x - x = 126.126126… - 0.126126126…
- Simplifying the right side gives: 999x = 126
- Solve for x by dividing both sides of the equation by 999: x = 126/999
- Simplify the fraction if possible: x = 14/111
Condition 3: Repeating pattern with non-repeating digits (e.g., 0.12666…)
- Identify the non-repeating part and the repeating block of digits.
- Set up an equation where x represents the entire repeating pattern: x = 0.12666…
- Multiply both sides of the equation by a power of 10 that matches the number of decimal places in the repeating block. In this case, we multiply by 100 because there are two non-repeating digits after the decimal point: 100x = 12.666…
- Subtract the original equation from the multiplied equation: 100x - x = 12.666… - 0.12666…
- Simplifying the right side gives: 99x = 12.54
- Solve for x by dividing both sides of the equation by 99: x = 12.54/99
- Simplify the fraction if possible: x = 19/150
Remember to simplify the fractions obtained in the final steps if possible.
