Which number is a rational terminating decimal?

5/11

7/8

sqrt(12)

sqrt(39)

1/3

1 answer

5/11 and 7/8 are rational terminating decimals because they can be expressed as fractions of integers.
5/11 = 0.454545... (repeating decimal)
7/8 = 0.875 (terminating decimal)

sqrt(12) and sqrt(39) are irrational numbers because they cannot be expressed as a fraction of integers, and their decimal representations would go on forever without repeating or terminating.

1/3 is a rational number but not a terminating decimal. Its decimal representation is 0.333333... (repeating decimal).
