What other way can -4 be represented as a rational number?
The rational number -4 can also be represented as -4/1 or 8/(-2), or any other equivalent fraction in the form of -4/n, where n is a non-zero integer.
The number -4 can be represented as a rational number using the ratio of two integers. To find another representation, we can use the fact that any non-zero rational number can be written in the form of a fraction a/b, where a and b are integers with no common factors other than 1.
One way to represent -4 as a rational number is: -4/1. Here, a = -4 and b = 1.
However, there are infinite ways to represent -4 as a rational number since we can multiply both the numerator and denominator by the same non-zero integer. For example, -8/2 and 16/4 are also different ways to represent -4 as a rational number.
