\n" ); document.write( "Since 5 goes into 15, we'll use that.
\n" ); document.write( "3/5 = how many 15ths?
\n" ); document.write( "Multiply by 3 across
\n" ); document.write( "3*3 = 9; 5*3 = 15
\n" ); document.write( "9/15
\n" ); document.write( "Now add the 4/15ths
\n" ); document.write( "9 pieces of pizza in a 15 piece pie + 4 pieces of pizza in a 15 piece pie =

\n" ); document.write( "13/15
