Answer:
8
Step-by-step explanation:
A way to solve it is to make 4 parts of water and 2 parts orange concentrate into a fraction. That would create 4/2. Next, the problem tells you that Lexia has put 16 cups of water. The numerator 4 represents the amount of water where as 2 represents orange concentrate. If 16 represents water also that now makes the equation 4/2=16/x. To get 4 to 16 you multiply by 4, therefore you must do the same to the denominator 2 and multiply it by 4. You end up with 8 know making the equation read 4/2=16/8.
