\n" ); document.write( " In order to subtract these two fractions, these fractions need to have a common denominator.
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " In order to do that, we simply find that the LCM of 7 and 3 is 21 (note: if you need help with finding the LCM, check out this solver)
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " Now we need to get each denominator to 21

\n" ); document.write( "

\n" ); document.write( " \"6%2F21-7%2F21\" Multiply \"1%2F3\" and \"%287%2F7%29\" to get \"7%2F21\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " Since both fractions have a common denominator of 21, we can now combine the fractions
