Calculator: https://www.omnicalculator.com/everyday-life/dilution-ratio

If I type in the dilution ratio and final volume it calculates the concentrate amount and water amount but I don't know how it does that and want to find out how it does that

Say I'm diluting a chemical at 10:1 (that's 11 total parts) for a final volume of 240 ml. 240 ml / 11 = 21.8 ml of chemical. Now to find the water: 240 - 21.8 = 218.2 ml.
