Question 2: Which of the following fractions cannot be written as a finite decimal?

\(\frac{{ – 10}}{{72}} = \frac{{ – 5}}{{36}}\text{ whose denominator is }36 = {2^2}{.3^2} \text{ has 3 as a prime divisor other than 2 and 5. Hence } \frac{{ – 10}}{{72}}\text{ cannot be written as a finite decimal. } \)
