solve the following equation for ( r ).
( 3 = \frac{r}{n} )

Explanation:

Step1: Multiply both sides by N

To isolate \( r \), we multiply both sides of the equation \( 3 = \frac{r}{N} \) by \( N \). This gives us \( 3 \times N = \frac{r}{N} \times N \).

Step2: Simplify the equation

Simplifying both sides, the \( N \) in the numerator and denominator on the right side cancels out, and we are left with \( 3N = r \), or \( r = 3N \).

Answer:

\( r = 3N \)
