\n" ); document.write( "\n" ); document.write( "Lowest common denominator means: What is the smallest number that is evenly divisible by both of the denominators?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "100 evenly divides 100, 200, 300, 400, 500...and so on.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "60 evenly divides 60, 120, 180, 240, 300 Ah-ha!! Both of them evenly divide 300, and that is the lowest common denominator. Actually you don't technically need the lowest common denominator, you just need a common denominator. In the end, 600 would work just as well. It is just that using the LCD allows you to use smaller numbers and less ugly arithmetic.\r
