Mix Ratios & Percentages
HOW TO CALCULATE PERCENTAGE IF MIX RATIO IS KNOWN
Divide 1 by the total number of parts (water + solution).
For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9).

If your mix ratio is 4:1 or 4 parts water to 1 part solution, there are (4 + 1) or 5 parts. The mixing percentage is 20% (1 divided by 5).
HOW TO CALCULATE MIX RATIO IF PERCENTAGE IS KNOWN
(100 – the percentage): percentage
For example, if your percentage is 4%, take 100 – 4 (which is 96), so your mix ratio is 96:4 which can then be reduced to 24:1.
Need another example?
If your percentage is 10%, take 100 – 10 (which is 90), so your mix ratio is 90:10 which can be reduced to 9:1.
