Proctice \( \frac{r}{3}=9 \)

To solve the equation \( \frac{r}{3}=9 \), you can start by multiplying both sides by 3 to isolate \( r \). So, \( r = 9 \times 3 \), which gives you \( r = 27 \). It's that simple! Remember, when you're solving equations, keeping the operations balanced is key to finding the correct solution. If you encounter similar equations, double-check your multiplication and division steps to avoid common pitfalls. A frequent mistake is to miscalculate or forget to apply the operation to both sides, which leads to incorrect solutions. Practice makes perfect, so keep those mathematical muscles flexing!
