Question 883909
the instructions say that the solution requires three parts water to1 part of the concentrated fluid 

your colleague once about 1.5 litres of cleaning solution how much concentrated fluid and how much water will they require 
round your calculations to the nearest hundred ml.
-----
Requirement:
3 water/ 1 pt concentrate

-------
Your Problem
Let amt of concentrate be "x"
Then amt of water is "3x"
-----
Equation:
x + 3x = 1.5 litres
4x = 1.5 litres
---
x = (3/2)/4 = 3/8  = 0.375 litres (amt of concentrate needed)
3x = 3*0.375 = 1.125 litres (amt of water needed)
