Explanation

Converting a repeating decimal to a fraction can seem challenging, but it can be done using a simple process. Follow the steps below to find the answer.

 

Step 1: Identify the repeating part of the decimal. Here, 0.666666666667 has a repeating decimal of 6.

Step 4: Subtract the original x from this equation: 10x - x = 6.666666666667 - 0.666666666667 9x = 6

 

Step 5: Solve for x by dividing both sides by 9: x = 6/9

 

Step 6: Simplify the fraction by dividing both the numerator and the denominator by their GCD, which is 3: 6/9 = 2/3

 

Thus, 0.666666666667 can be approximated as the fraction 2/3.
