| Abstract: | This article is stressed on dealing with the regularities of supplied mathematical problems which are about the proportioning of solutinon, solute and solvent. It enumerates general types of such problems and expounds how to grasp the basic relationship between solution, solute and solvent, It also tells how to find out the equal relations hidden in the problems, establish elements and give eguations by diagraming. |
