Year 12s: what will be the first way you research your future options? >>

Stuck on a ratio maths problem

A certain preparation consists of liquids x, y and z in the proportion 3: 2: 1

How many millilitres of the preparation can be made from a stock of materials consisting of 18 millilitres of x, 10 millilitres of y, and 5 millilitres of z?

Please explain to me how to go about this, thanks

The ratio must be 3:2:1 so e.g. you could have 6ml of x, 4ml of y and 2ml of z.

So that would give you 12ml of preparation.

But that's not the maximum. What's the largest amount you could make?
