Question

What is the numerical coefficient in $ab$?

• A. $1$
• B. $0$
• C. $a$
• D. $b$

Answer 1

The correct option is A $1$

$\underset{–}{\text{Numerical Coefficient}:}$
A numerical coefficient is a number that is the multiplier of the variables in a term. For example, $3$ is the numerical coefficient of the term $3x^2.$

We are given with an algebraic term $xy$.
$xy$ can be represented as:
$xy=1\times xy=\left(1\right)xy$
As per the above figure, we can say that $1$ is the numerical coefficient in the algebraic term $xy$. Therefore, option (a.) is the correct answer.
