\n" ); document.write( "I don't know what the reference you are using calls \"the five step strategy\"....

\n" ); document.write( "Maybe something like this:

\n" ); document.write( "(1) Define a variable
\n" ); document.write( "Let x be the number we are looking for.

\n" ); document.write( "80% is 0.80 or 4/5.

\n" ); document.write( "(2) Write the equation that says 80% of the number is 224.
\n" ); document.write( " $\"%284%2F5%29x=224\"$

\n" ); document.write( "(3) Solve the equation: multiply both sides of the equation by the reciprocal of 4/5.
\n" ); document.write( " $\"%285%2F4%29%284%2F5%29x=%285%2F4%29%28224%29\"$
\n" ); document.write( " $\"x=5%28224%2F4%29=5%2856%29=280\"$

\n" ); document.write( "(4) Answer the question.
\n" ); document.write( "80% of 280 is 224.

\n" ); document.write( "That's 4 steps; perhaps your five step strategy uses two separate steps to do one of the four I used.

\n" ); document.write( " \n" ); document.write( "

\n" );
