\n" ); document.write( "\"the ratio of girls to boys is 1 to 2\" means we could have any of the following scenarios:
\n" ); document.write( "1 girl & 2 boys
\n" ); document.write( "2 girls & 4 boys
\n" ); document.write( "3 girls & 6 boys
\n" ); document.write( "4 girls & 8 boys
\n" ); document.write( "and so on\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Whatever the number of girls there are, double it to get the number of boys.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since we have 18 girls, we must have 2*18 = 36 boys\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Another way to solve:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "g = number of girls = 18
\n" ); document.write( "b = number of boys = unknown\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "g/b = 1/2
\n" ); document.write( "18/b = 1/2
\n" ); document.write( "18*2 = b*1
\n" ); document.write( "36 = b
\n" ); document.write( "b = 36 boys\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Feel free to explore other alternative methods to solving.
