Question

an integer is either a whole number or the opposite of a whole number.
which of these numbers is an integer?
-24
-0.9
\\(\frac{5}{15}\\)
13.01
integers can be whole numbers: 0, 1, 2, 3, ...
integers can also be the opposites of whole numbers: -1, -2, -3, ...

Explanation:

Step1: Recall integer definition

Integers include whole numbers (0, 1, 2, ...) and their opposites (-1, -2, -3, ...), also no decimals/fractions (unless simplifies to integer).

Step2: Analyze each number

• \(-24\): Negative whole number, so integer.
• \(-0.9\): Decimal (not integer).
• \(\frac{5}{15}=\frac{1}{3}\): Fraction (not integer).
• \(13.01\): Decimal (not integer).

Answer:

\(-24\)
