\n" ); document.write( "Given the ratio of 3 boys to every 4 girls,...

\n" ); document.write( "Let 3x = # of boys
\n" ); document.write( "Let 4x = # of girls

\n" ); document.write( "That is nearly always the best way to start on a problem like this where a ratio is given.

\n" ); document.write( "The total number of preschoolers is 245:

\n" ); document.write( "3x+4x=245
\n" ); document.write( "7x=245
\n" ); document.write( "x=245/7=35

\n" ); document.write( "ANSWER: The number of boys is 3x = 3(35) = 105

\n" ); document.write( "
