This ratio can be shown as 3/5 also. (6/10=3/5)
\n" ); document.write( "Now, since there are 30 girls, you make this into a set of fractions that equal each other.\r
\n" ); document.write( "\n" ); document.write( "3/5 = 30/x
\n" ); document.write( "Now, 3*10 = 30, so you can multiply by 10 in the denominator as well. 5*10 = 50.
\n" ); document.write( "So there are 50 boys in the geometry class.
