Call what she started with, w, for \"whole amount she started with\". This is a number, but we do not know its value.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Try to form a step-wise process. First part,\"w-%281%2F3%29w\". Simplify this NOW.
\n" ); document.write( "\"%282%2F3%29w\" is what she has.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Second part, \"%282%2F3%29w-%281%2F4%29%282%2F3%29w\" is what she has when spent the second part. Simplify this now. LCD is 12, seeing denominators as factors being 4 and 3.
\n" ); document.write( "\"%282%2F3%29w%284%2F4%29-%281%2F4%29%282%2F3%29w\"
\n" ); document.write( "\"%288%2F12%29w-%282%2F12%29w\"
\n" ); document.write( "\"%286%2F12%29w\"
\n" ); document.write( "\"%281%2F2%29w\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Third part, spending one fifth of the current amount at the museum.
\n" ); document.write( "\"%281%2F2%29w-%281%2F5%29%281%2F2%29w\", and LCD is 10.\r
\n" ); document.write( "\n" ); document.write( "\"%285%2F10%29w-%281%2F10%29w\"
\n" ); document.write( "\"%284%2F10%29w\"
\n" ); document.write( "\"%282%2F5%29w\"
\n" ); document.write( "-
\n" ); document.write( "Finally, we are told that this amount is $32.40; so we have
\n" ); document.write( "\"%282%2F5%29w=32.40\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "How do you undo multiplication by a fraction? Multiply by the reciprocal. Do this to BOTH sides of the equation! What happens to the left-side member? What happens to the right-side member?
