1 2/3 + 3 1/4
\n" ); document.write( "Convert to fractions first.
\n" ); document.write( "1 2/3 = 5/3
\n" ); document.write( "3 1/4 = 13/4
\n" ); document.write( "-----------
\n" ); document.write( "=(5/3) + (13/4)
\n" ); document.write( "Now find a common denominator. In class, they fret about the LCD, least common denominator, but anyone will do. What ALWAYS works is to multiply the 2 DENs.
\n" ); document.write( "3*4 = 12
\n" ); document.write( "In this case, it happens to be the LCD, but it isn't always, but it always works.\r
\n" ); document.write( "\n" ); document.write( "Now, find what 5/3 is with the DEN of 12. You multiply NUM and DEN by 4.
\n" ); document.write( "5/3 = 20/12
\n" ); document.write( "Do the same with 13/4, but multiply by 3 to get the DEN of 12.
\n" ); document.write( "13/4 = 39/12
\n" ); document.write( "--------
\n" ); document.write( "Then add them.
\n" ); document.write( "(20/12) + (39/12) = 59/12. That's it.
\n" ); document.write( "You can make it a mixed fraction. 59/12 = 4 11/12, but I see no advantage to that.
\n" ); document.write( "BTW, I have a 5 yr old niece named Jasmine.
