Answer to Problem 59HP
False
Explanation of Solution
Given: Determine whether the following statement is true or false. If true explain your reasoning. If false give a counterexample.
A rational number is always an integer.
The statement is false.
A rational number is always an integer
Because terminating and repeating decimals are also rational numbers but they are not integers.
For example:
