What does numerical coefficient mean?

What does numerical coefficient mean?

A numerical coefficient is the number that comes before the variables in a mathematical expression.

Here are some examples of the coefficients.

Examples of numerical coefficients

Example 1.

5x

The numerical coefficient is 5.

Example 2.

10xy

The numerical coefficient is 10.

Example 3.

34x3y2

The numerical coefficient is 34.

Example 4.

(15x3y2)/27

The numerical coefficient is 15/27. Why?

(15x3y2)/27 =
(15/27)x3y2

The (15/27) is the number that comes before the variables.

As you see, the numerical coefficient can be a fraction.
