You can put this solution on YOUR website!
Gallons? Percents 12, 20, 15? What are the densities of these concentrations? What form of percent is meant?\r

\n" ); document.write( "\n" ); document.write( "In clearer wording, the two kinds of information you must first be given are the densities of the solutions and how the percent concentrations are expressed: weight per weight, or weight per volume. These pieces of information may be necessary. Without them, the problem description is incomplete.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "One could ignore densities and the kind of percentages meant, but this would only be a bad estimate of the truthful answer. \n" ); document.write( "
