Q. Evaluate the expression for

j = 12

and

k = -12

. Simplify your answer.

\newline

\frac{j - k}{j} =

\_\_\_\_

Write Expression with Given Values: Write down the expression with the given values for $j$ and $k$ . $\newline$ Substitute $j = 12$ and $k = -12$ into the expression $\frac{j - k}{j}$ . $\newline$ Expression: $\frac{12 - (-12)}{12}$
Perform Substitution: Simplify the expression by performing the subtraction in the numerator. $\newline$ $12 - (-12) = 12 + 12 = 24$ $\newline$ Now the expression is $\frac{24}{12}$ .
Simplify Numerator: Divide the numerator by the denominator to simplify the fraction. $\frac{24}{12} = 2$
