repeating digits) or using number lines can clarify what’s happening mathematically.

Sample Problem Walkthrough Using a Worksheet Approach

To illustrate how a repeating decimals to fractions worksheet might guide a learner, here’s

an example with the decimal 0.727272…

**Step 1:** Let x = 0.727272…

**Step 2:** Since the repeating part “72” has two digits, multiply both sides by 100 to

move the decimal two places:

100x = 72.727272…

**Step 3:** Subtract the original x from this equation:

100x – x = 72.727272… – 0.727272…

99x = 72

**Step 4:** Solve for x:

x = 72 / 99

**Step 5:** Simplify the fraction:

Divide numerator and denominator by 9:

72 ÷ 9 = 8

99 ÷ 9 = 11

So, x = 8/11

This stepwise approach is exactly what worksheets aim to reinforce through multiple

similar exercises.
