When working with proportions like this, always remember:
\n" ); document.write( " $\"+a%2Fb+=+c%2Fd+\"$ Cross multiply and you will find that ad = bc

\n" ); document.write( "Now we will set this up using your data:
\n" ); document.write( " $\"+z%2F7+=+16%2F56+\"$ cross multiplying gives us:
\n" ); document.write( " $\"+56z+=+cross%287%2A16%29+=+112+\"$

\n" ); document.write( "Divide both sides by 56:
\n" ); document.write( " $\"+56z%2F56+=++112%2F56+\"$
\n" ); document.write( "and we find that
\n" ); document.write( "z = 2
\n" ); document.write( "and bob's your uncle!\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
