Question 1186727
.
Ibuprofen for infants comes in a liquid form and contains 55 milligrams of ibuprofen for each 1.375 milliliters of liquid. 
If a child is to receive a dose of 50 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.
~~~~~~~~~~~~~~~~



            As the post asks to write an equation, but do not solve it, I make it exactly as requested.



<pre>
Use this proportion


    {{{55/1.375}}} = {{{50/L}}},


where L represents milliliters of the liquid solution.


The proportion says that the concentration of the Ibuprofen is the same in both cases.


From the [proportion,


    L = {{{(50*1.375)/55}}}  milliliters.

Solved, answered and explained.
