\n" ); document.write( "Given the ratio of 8:9 of girls to boys, one common way to start working the problem is to let the number of girls be 8x and the number of boys be 9x.

\n" ); document.write( "Then, given that the total number of students is 340,

\n" ); document.write( "\"8x%2B9x+=+340\"
\n" ); document.write( "\"17x+=+340\"
\n" ); document.write( "\"x+=+340%2F17+=+20\"

\n" ); document.write( "ANSWER: The number of boys is 9x = 9(20) = 180.

\n" ); document.write( "
