Question

Hey I need help with a problem 3/k = 5/15

Answer 1

`(3)/(k)=(5)/(15)`

k is dividing on the left, then it will multiply on the right

15 is dividing on the right, then it will multiply on the left

`\begin{gathered} 3\cdot15=5\cdot k \\ 45=5\cdot k \end{gathered}`

5 is multiplying on the right, then it will divide on the left

`\begin{gathered} (45)/(5)=k \\ 9=k \end{gathered}`
