\r
\n" ); document.write( "\n" ); document.write( "You can. a/b=a/c Divide both sides by a/c thus:

\r
\n" ); document.write( "\n" ); document.write( "(a/b)/(a/c) = 1 To divide by a fraction, multiply by the reciprocal:

\r
\n" ); document.write( "\n" ); document.write( "(a/b)*(c/a) = 1 Cancel the a c/b=1 multiply both sides by b:


\n" ); document.write( "c=b.

\r
\n" ); document.write( "\n" ); document.write( "If you initially cancel the a's then 1/b = 1/c Multiply both sides by b and both sides by c


\n" ); document.write( "c=b which is the same answer. \n" ); document.write( "

\n" );
