Answer 1

The correct response is:

It is an integer but not a whole number.

Explanation:

• An integer is any whole number (positive, negative, or zero), and -9 is an integer.
• A whole number is defined as a non-negative integer (0, 1, 2, 3, ...). Since -9 is negative, it is not considered a whole number.

Answer 3

The price of gas advertised at the rate of $3.39910 per gallon should be written strictly as a decimal as:

3.399

This represents the cost of one gallon in dollars. The additional digits after the last digit may represent a small fraction of a cent but are typically not shown in standard pricing. Therefore, the correct response is 3.399.
