if x onions cost r cents, how many onions can be bought with d dollars?
\n" ); document.write( "-----------------
\n" ); document.write( "d dollars = 100d cents
\n" ); document.write( "an onion costs r/x cents --> x/r onions/cent
\n" ); document.write( "100d * (x/r) = # of onions
\n" ); document.write( "= 100dx/r
\n" ); document.write( "-----------
\n" ); document.write( "multiplying and dividing the units, not just the numbers or variables, makes it clear.
\n" ); document.write( "
\n" );
