Final answer:
A fraction that can be converted into a terminating or repeating decimal is a rational number.
Step-by-step explanation:
True. A fraction that can be converted into a terminating or repeating decimal is a rational number.
A rational number is any number that can be expressed as a fraction where the numerator and denominator are both integers. When a fraction is converted into a decimal, it can either terminate (end) or repeat indefinitely.
For example, the fraction 1/4 can be converted to the decimal 0.25, which terminates. The fraction 1/3 can be converted to the decimal 0.333..., which repeats.
