Question

In the algebraic expression $\frac{x}{5} + \frac{4 y}{5} + 2$ , the sum of numerical coefficients of $x & y$ is

Open in App

Solution

In the algebraic expression $\frac{x}{5} + \frac{4 y}{5} + 2$ ,
the numerical coefficient of $x$ is $\frac{1}{5}$ and the numerical coefficient of $y$ is $\frac{4}{5}$ .
Hence, the sum of numerical coefficients of $x & y = \frac{1}{5} + \frac{4}{5} = \frac{5}{5} = 1$
