Question
Write the repeating decimal as a fraction..0812
Solution 1
To write the repeating decimal .0812 as a fraction, we can follow these steps:
Step 1: Let x be the repeating decimal .0812.
Step 2: Multiply both sides of the equation by 10000 (since there are four decimal places) to eliminate the decimal point: 10000x = 81.12
Step 3: Subtract x from both sides of the equation to isolate the repeating decimal: 10000x - x = 81.12 - .0812 9999x = 81.0388
Step 4: Divide both sides of the equation by 9999 to solve for x: x = 81.0388 / 9999
Step 5: Simplify the fraction if possible. In this case, the fraction cannot be simplified further.
Therefore, the repeating decimal .0812 can be written as the fraction 81.0388 / 9999.
