Answer 1

A rational terminating decimal is a decimal that has a finite number of digits after the decimal point. To determine which of the given options is a rational terminating decimal, we should look at each one:

1. **13**: This is a whole number and can be represented as a decimal (13.0). It is a terminating decimal.
2. **1 third (1/3)**: This is a repeating decimal (0.333...), not terminating.
3. **√39**: This is an irrational number because it cannot be simplified to a fraction that is a terminating decimal.
4. **78**: This is a whole number and can be represented as a decimal (78.0). It is a terminating decimal.
5. **7 eighths (7/8)**: This is equal to 0.875, which is a terminating decimal.
6. **√12**: This is also an irrational number because it cannot be simplified to a fraction that is a terminating decimal.
7. **511**: This is a whole number and can be represented as a decimal (511.0). It is a terminating decimal.
8. **5 over 11 (5/11)**: This is a repeating decimal (0.4545...), not terminating.

From the options, the numbers that are rational terminating decimals are **13, 78, 7/8, and 511**.

However, if you are looking for just one response, the best options would be **13** (since it is simple and straightforwardly a terminating decimal). If you need to select just one, then **13** could be considered your answer.
