The ratio of the number of boys to the number of girls in a club was 9:8.
\n" ); document.write( "Let # of girls be 9x
\n" ); document.write( "Then # of boys is 8x
\n" ); document.write( "--------------------------------------
\n" ); document.write( "1/2 of the number of girls left the club and there were 15 more boys than girls.
\n" ); document.write( "Equation:
\n" ); document.write( "8x = (1/2)9x + 15
\n" ); document.write( "8x = 4.5x + 15
\n" ); document.write( "3.5x = 15
\n" ); document.write( "x = 15/3.5
\n" ); document.write( "---
\n" ); document.write( "a. How many children were in the club at first?
\n" ); document.write( "9x+8x = 17x = 73 when rounded up
\n" ); document.write( "-------------
\n" ); document.write( "b. How many girls left the club?
\n" ); document.write( "4.5x = 20 when rounded up
