Final answer:
The numbers 2, 5, 1, 10, 13, and 1.0 are classified as whole numbers because they are non-negative and have no fractional or decimal component. -7.8, -5, and -8/4 are not whole numbers due to being either negative or having a fractional/decimal component.
Step-by-step explanation:
The question asks us to identify which of the following numbers can be classified as being a whole number: 2, 5, -7.8, 1, 10, 13, 1.0, -5, -8/4. A whole number is any number that is not a fraction or decimal, and it is also a non-negative number. This means negative numbers, fractions, and decimals are excluded from being whole numbers.
Amongst the given numbers, 2, 5, 1, and 10, and 13 are whole numbers. They are non-negative and have no fractional or decimal component. Here's a quick breakdown:
- 1.0 - Although it is written with a decimal, it is equivalent to 1 and is considered a whole number.
- -5 - This is a negative number and not a whole number.
- -8/4 - This is equivalent to -2, which is a negative number and not a whole number.
