Answer 1

Answer: Rational because it is a decimal that terminates.

Explanation:

A rational number can be expressed as a ratio/ fraction of two integers so there are several methods of knowing if a number is rational or irrational.

One such way is if it is a decimal that terminates. A terminating decimal is one that has a set amount of numbers after the decimal and hence does not continue forever. This number is rational because it can be expressed as a fraction.

0.84375 in fraction form would be, 84,375/100,000.
