5/8 - 3/10
\n" ); document.write( "Make their denominators equal first. Their LCM (least common multiple) is 40, so 40 is going to be the denominator.
\n" ); document.write( "5/8 = 25/40 (40/8 is 5. 5x5=25)
\n" ); document.write( "3/10 = 12/40 (40/10 is 4. 4x3=12)\r
\n" ); document.write( "\n" ); document.write( "You can now subtract because they have the same denominator. 25-12 = 13 is the numerator.
\n" ); document.write( "Therefore the answer is 13/40.
