The sign rules for simplifying expressions with rational numbers are similar to those for integers in that they both follow the same basic principles: a positive times a positive is positive, a negative times a negative is positive, and a positive times a negative is negative. This consistency ensures that the operations on rational numbers maintain the same logical structure as those on integers. Consequently, when performing operations like addition, subtraction, multiplication, or division, the sign of the result can be determined using the same rules regardless of whether the numbers involved are rational or integers.

Are all rational numbers are integers?

No, not all rational numbers are integers. All integers are whole numbers, but a non-whole number can be rational if the numbers after the decimal point either 1. end or 2. repeat. So, sometimes rational numbers are integers, sometimes they're not. But all integers are rational numbers.
