Let one number be x. The other number is then (105-x).
\r
\n" ); document.write( "\n" ); document.write( "Then we have:
\r
\n" ); document.write( "\n" ); document.write( "\"x%2A%281%2F2%29=%28105-x%29%2A%281%2F3%29\" given
\r
\n" ); document.write( "\n" ); document.write( "\"6%2Ax%2A%281%2F2%29=6%2A%28105-x%29%2A%281%2F3%29\" multiply by 6 on each side to eliminate fractions
\r
\n" ); document.write( "\n" ); document.write( "\"3x=2%2A%28105-x%29\"
\r
\n" ); document.write( "\n" ); document.write( "\"3x=210-2x\"
\r
\n" ); document.write( "\n" ); document.write( "\"5x=210\"
\r
\n" ); document.write( "\n" ); document.write( "\"x=42\"
\r
\n" ); document.write( "\n" ); document.write( "So if one number is 42, the other number would be 63.
\r
\n" ); document.write( "\n" ); document.write( "However, we are not quite finished, because we can also set it up this way:
\r
\n" ); document.write( "\n" ); document.write( "\"x%2A%281%2F3%29=%28105-x%29%2A%281%2F2%29\" given
\r
\n" ); document.write( "\n" ); document.write( "\"6%2Ax%2A%281%2F3%29=6%2A%28105-x%29%2A%281%2F2%29\" multiply by 6 on each side to eliminate fractions
\r
\n" ); document.write( "\n" ); document.write( "\"2x=3%2A%28105-x%29\"
\r
\n" ); document.write( "\n" ); document.write( "\"2x=315-3x\"
\r
\n" ); document.write( "\n" ); document.write( "\"5x=315\"
\r
\n" ); document.write( "\n" ); document.write( "\"x=63\"
\r
\n" ); document.write( "\n" ); document.write( "And of course, if one number is 63, the other number must be 42.
\r
\n" ); document.write( "\n" ); document.write( "This proves that no matter which number you multiply by the fractions of 1/2 and 1/3, you will get the same answer.
\r
\n" ); document.write( "\n" ); document.write( "In other words, the two numbers will always be 63 and 42.
\r
\n" ); document.write( "\n" ); document.write( "I hope this helps!
\n" ); document.write( "
