Let's find a common denominator first. What number do both 10 and 6 go into? I can see right off that 30 will work (it doesn't HAVE to be the lowest common denominator; you can always reduce later).
\n" ); document.write( "\"3%2F10\"= how many 30ths? Multiply top and bottom by 3 to get \"9%2F30\"
\n" ); document.write( "\"1%2F6\"= how many 30ths? Multiply top and bottom by 5 to get \"5%2F30\"
\n" ); document.write( "Add them together
\n" ); document.write( "\"9%2F30\"+\"5%2F30\"=\"14%2F30\"
\n" ); document.write( "If he spends \"14%2F30\", then there will be 30-14, or \"16%2F30\"left over.
\n" ); document.write( "What number can you reduce that fraction to?
\n" ); document.write( "
\n" );
