Question

A number which precedes a variable and that can be expressed in the form a/b (where a and b are integers) is called a ___ coefficient.

Answer 1

Rational.

Explanation:

A number which precedes a variable is called a coefficient. Now, if that coefficient can be expressed in the form a/b with a and b integers, then a/b is a rational number (those are the fractions and the integers), thus that number is a rational coefficient.

Answer 2

The answer is: Rational coefficient.

The explanation for this answer is shown below:

1. By definition, a rational number has the form
`(a)/(b)` where
`a` is the numerator and
`b` is the denominator. The numerator and the denominator are integers.

2. By definition, integers numbers includes positive numbers, negative numbers and zero.

3. Keeping the information above on mind, you can conclude that the answer is: Rational coefficient.

4. For example:

`(1)/(3)x`

`(1)/(3)` is a rational coefficient.
