What is 1.21 repeating as a fraction? The correct answer and explanation is: To convert the repeating decimal 1.2121‾1.21\overline{21} into a fraction, follow these steps: Thus, 1.2121‾1.21\overline{21} as a fraction is 4033\frac{40}{33}. This process works because multiplying by powers of 10 shifts the decimal point, and subtracting removes the repeating part, leaving a solvable equation.
