A. 1/8 B. 1/5 C. 1/3 D. 2/3 E. 3/4 Convert each fraction to a decimal... A. 1/8 = 0.125 (3 digits to the right of the decimal point) B. 1/5 = 0.2 (1 digit to the right of the decimal point) NOTE: The only way to have FEWER than 1 digit to the right of the decimal point is to have ZERO digits to the right of the decimal point. This occurs only when the fraction evaluates to be an integer. Since none of the remaining fractions evaluate to be an integer, the correct answer is B That said, let's perform the remaining conversions for "fun" C. 1/3 = 0.333333... (infinitely many digits to the right of the decimal point) D. 2/3 = 0.66666.... (infinitely many digits to the right of the decimal point) E. 3/4 = 0.75 (2 digits to the right of the decimal point) Answer: B Cheers, Brent _________________ Brent Hanneson â€“ Creator of GMATPrepNow.com Use my video course along with Sign up for free Question of the Day emails And check out all of these free resources GMAT Prep Now's comprehensive video course can be used in conjunction with Beat The GMATâ€™s FREE 60-Day Study Guide and reach your target score in 2 months! ### GMAT/MBA Expert GMAT Instructor Joined 04 Oct 2017 Posted: 551 messages Followed by: 11 members Upvotes: 180 Quote: If each of the following fractions were written as a decimal, which would have the fewest number of digits to the right of the decimal point?

To find the number of digits to the right of the decimal point, we need to convert the fractions to decimals. $$\frac{1}{8}=0.125$$ $$\frac{1}{5\ }=0.2$$ $$\frac{1}{3}=0.3333...$$ $$\frac{2}{3}=0.6666...$$ $$\frac{3}{4}=0.75$$ We can see that 1/5 has the fewest number of digits to the right of the decimal point. Therefore, Option B is correct. I am available, if you'd like any follow up. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.
