1. Set the repeating decimal as "x": x = 0.474747...
2. Multiply both sides of the equation by 100 to eliminate the decimal: 100x = 47.474747...
3. Subtract the original equation (x = 0.474747...) from the equation in step 2: 100x - x = 47
4. Simplify the equation: 99x = 47
5. Divide both sides of the equation by 99 to solve for x: x = 47/99
