After simplifying ( \frac{91}{140} ), what type of decimal expansion will it have?

Answer and explanation

Correct answer: Terminating

A rational number has a terminating decimal expansion when, after simplification, the denominator has no prime factors other than 2 and 5. First reduce the fraction by dividing 91 and 140 by their common factor 7: \\(\frac{91}{140}=\frac{13}{20}\\). The denominator 20 factors as \\(2^2\times5\\), so it contains only the allowed prime factors.

Indeed, \\(\frac{13}{20}=\frac{65}{100}=0.65\\), which ends after two decimal places. Therefore the expansion is terminating, and option A is correct. It is not non-terminating recurring because no factor such as 3, 7, or 11 remains in the simplified denominator. Simplifying before judging the decimal type is essential.
