1. The problem asks: Which number is not equal to a recurring decimal? 2. A recurring decimal is a decimal number where one or more digits repeat infinitely after the decimal point. 3. Fractions with denominators having only 2 and/or 5 as prime factors produce terminating decimals, not recurring decimals. 4. For example, $\frac{1}{2} = 0.5$ (terminating), $\frac{1}{3} = 0.333...$ (recurring). 5. Therefore, any fraction whose denominator contains prime factors other than 2 or 5 will have a recurring decimal. 6. So, the answer is: numbers with denominators that are powers of 2 and/or 5 (like $\frac{1}{2}$, $\frac{3}{25}$) are not recurring decimals. Final answer: Numbers with terminating decimals (denominators with only 2 and/or 5 as prime factors) are not equal to recurring decimals.
