Ibuprofen for infants comes in a liquid form and contains \(40\) milligrams of ibuprofen for each \(1\) milliliters of liquid. If a child is to receive a dose of \(60\) milligrams of ibuprofen, how many milliliters of liquid should they be given?
Assume \(l\) milliliters of liquid should be given. Write an equation to model this scenario. There is no need to solve it.
