Write this problem exactly as it is stated:
\n" ); document.write( ".
\n" ); document.write( " $\"+21+=+0.35%2AX\"$
\n" ); document.write( ".
\n" ); document.write( "Note that 0.35 is equivalent to 35%. X is the unknown number you are looking for.
\n" ); document.write( ".
\n" ); document.write( "To find X, the number you are looking for, divide both sides of the equation by 0.35.
\n" ); document.write( ".
\n" ); document.write( " $\"21%2F0.35+=+cross%28%280.35%29%29%2AX%2Fcross%28%280.35%29%29\"$
\n" ); document.write( ".
\n" ); document.write( "Note that on the right side the 0.35 factor in the numerator cancels with the 0.35 factor in
\n" ); document.write( "the denominator and you are left with just X on the right side. On the left side the answer
\n" ); document.write( "to $\"21%2F0.35\"$ is $\"60\"$ .
\n" ); document.write( ".
\n" ); document.write( "So the answer to this problem is $\"X+=+60\"$ . 35% of 60 is 21.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to see how to solve this problem. In the statement of the problem, the
\n" ); document.write( "word \"is\" means \"equals\" and \"unknown number\" means a variable, often written as \"X\" or
\n" ); document.write( "some other letter. And \"35 percent of\" means \"35% times\" or \"0.35 times.\" \n" ); document.write( "

\n" );
