You can put this solution on YOUR website!
p is unknown quantity of 40 percent alcohol to start with.
\n" ); document.write( "\"40%2Ap%2F%28p%2B2%29=35\"
\n" ); document.write( "\"40p=35%28p%2B2%29\"
\n" ); document.write( "\"40p=35p%2B70\"
\n" ); document.write( "\"5p=70\"
\n" ); document.write( "\"p=70%2F5=%287%2A2%2A5%29%2F5\"
\n" ); document.write( "\"p=14\" gallons\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The pizza:
\n" ); document.write( "5 slices is \"10%2F16\" of the whole pizza.
\n" ); document.write( "1 slice is \"%281%2F5%29%2810%2F16%29=2%2F16=1%2F8\" of the whole pizza.
\n" ); document.write( "Without further calculation on paper or on keyboard/screen, one-eighth of the pizza remains. (\"mental\" arithmetic may be sufficient, as long as analyzed well to find \"1%2F8\" pizza for 1 slice).
\n" ); document.write( "-
\n" ); document.write( "How much was eaten? \"7%2F8\", 5 eighths plus 2 eighths.
\n" ); document.write( "
\n" );
