Dividing by a rational number (other than zero) is simply multiplication by its reciprocal.
All integers are rational numbers. There are integers with an i behind them that are imaginary numbers. They are not real numbers but they are rational. The square root of 2 is irrational. It is real but irrational.
Fractions are not integers. They may or may not be rational numbers.
All integers are rational. Not all rational numbers are integers.
A rational number can be stated in the form a/b where and b are integers. Adding or multiplying such numbers always gives another number that can be expressed in this form also. So it is also rational.
did you get this off of big ideas learning
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.
The rules are the same.
Dividing by a rational number (other than zero) is simply multiplication by its reciprocal.
It the two rational numbers have different signs, then the answer will be negative, otherwise it will be positive.
It the signs of the two numbers that you are multiplying or dividing is the same, then the answer is positive, otherwise the answer is negative. Remember though, that division by 0 is not defined.

It's a positive number. Here's the rule: In multiplication and division . . . -- If both numbers have the same sign, then the result of multiplying or dividing them is positive. -- If the two numbers have different signs, then the result of multiplying or dividing them is negative.

Integers are aproper subset of rational numbers.
