You can put this solution on YOUR website!
The ratios are: 3:5:4
Without changing these ratios, I can also say:
+3%2F12+%2B+5%2F12+%2B+4%2F12+=+12%2F12+
Now the ratios are in terms of fractions of the whole mixture
Multiply both sides by +60+
+%28+3%2F12+%29%2A60+%2B+%28+5%2F12+%29%2A60+%2B+%28+4%2F12+%29%2A60+=+60+
+15+%2B+25+%2B+20+=+60+
------------------------
15 liters of water
25 liters of wax
20 liters of white spirits
------------------------
25 liters of wax are needed
