Question

words problem

 

Answer 1

Since 500 ml is one fifth OJ, then there is 100 ml of OJ per 500 ml of the fruit drink mixture.

That is, 100 ml of pure juice in 0.5 liters of mixture.

 

Now, 2.5 liters of the mixture is five times 0.5 liters, so there is 5 times 100 ml of pure juice in the mixture, that is, 500 ml of pure juice.
