Algebraic Version

\n" ); document.write( " $\"ModelSize+is+1%2F10+realSize\"$
\n" ); document.write( "
\n" ); document.write( " $\"42=1%2F10%2AReal+Size\"$
\n" ); document.write( "Multiply both sides by 10
\n" ); document.write( " $\"420=Real+Size\"$
\n" ); document.write( "The car is 420 centimeters long.
\n" ); document.write( "

\n" ); document.write( "If the model car is 1/10 of the real car, then 10 times the model car must be the size of the real car.
\n" ); document.write( "Because the model is 42cm, the real car must be 420 centimeters long. \n" ); document.write( "
