ANSWER
False, that is a mixed number
Step-by-step explanation
A proper fraction is a fraction where the denominator is greater than the numerator. On the other hand, an improper fraction is a fraction where the denominator is less than the numerator.
If we put a whole number and a proper fraction together we don't get an improper fraction unless we add those two numbers. Instead we'd have a mixed number.
For example:
If we add the whole number and the proper fraction:
We get an improper fraction.
Therefore, the given statement is false.
