You can put this solution on YOUR website!
You can either find a common denominator or express the fractions as decimals. What method do you prefer? I guess the decimal method is too easy, so let's do it the other way.\r
\n" ); document.write( "\n" ); document.write( "\"5%2F16\" compared to \"7%2F18\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Usually we find the LCD, but in this case it will be easier to just use the product of the denominators for the common denominator. That would be \"16%2A18\", and you don't even have to calculate it!\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In order to make a comparison, multiply the first fraction by \"18%2F18\" and the second by \"16%2F16\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"5%2F16\" compared to \"7%2F18\"
\n" ); document.write( "\"%285%2F16%29%2A%2818%2F18%29\" compared to \"%287%2F18%29%2A%2816%2F16%29\"
\n" ); document.write( "\"90%2F%2816%2A18%29\" compared to \"112%2F%2818%2A16%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This means that the second fraction is larger.
\n" ); document.write( "\"%287%2F18%29%3E%285%2F16%29\"\r
\n" ); document.write( "
