Which fraction equals 0.32 when expressed in simplest form?

• A. 8/25
• B. 2/25
• C. 16/50
• D. 32/100

Answer: (A)

Converting a decimal to a fraction and simplifying it to lowest terms is what’s being tested. 0.32 can be written as 32/100. Simplifying by dividing numerator and denominator by 4 gives 8/25. Since 8 and 25 have no common divisors other than 1, 8/25 is already in simplest form. That means 0.32 equals 8/25 in simplest terms. The other fractions either are not already in simplest form or don’t represent 0.32. For example, 16/50 reduces to 8/25, and 32/100 also reduces to 8/25, but they’re not the simplest form themselves. And 2/25 equals 0.08, which is not 0.32.
