A rational terminating decimal is a fraction that, when expressed as a decimal, ends after a finite number of digits.
Among the options provided, we can analyze each one:
- 5/11 - This results in a repeating decimal (0.454545...).
- 1/3 - This also results in a repeating decimal (0.333...).
- √39 - This is an irrational number and does not terminate.
- √12 - This is also an irrational number and does not terminate.
- 7/8 - This results in a terminating decimal (0.875).
The only option that is a rational terminating decimal is 7/8.
