You can put this solution on YOUR website!
$\"9%2F24\"$ and $\"15%2F40\"$ ---> proportion?
\n" ); document.write( ">>>Statement of equality, okay.
\n" ); document.write( " $\"%289%2F24%29=%2815%2F40%29\"$ , cross multiply
\n" ); document.write( " $\"9%2A40=15%2A24\"$
\n" ); document.write( " $\"360=360\"$ , Proportion
\n" ); document.write( "Another way,
\n" ); document.write( " $\"%289%2F24%29\"$ , divide both num & den by 3
\n" ); document.write( " $\"%283%2F8%29\"$ ----> A
\n" ); document.write( "And, $\"15%2F24\"$ , divide both num & den by 5
\n" ); document.write( " $\"3%2F8\"$ -----> B
\n" ); document.write( "As you see, $\"A=B\"$ , proportion.
