1/8 + 5/6 - 2/3
\n" ); document.write( "------------
\n" ); document.write( "To add or subtract fractions they must have
\n" ); document.write( "the same denominator.
\n" ); document.write( "-------------------
\n" ); document.write( "The denominator you want is called the least common denominator (lcm).
\n" ); document.write( "For your problem the lcm is 24 because it is the smallest number that
\n" ); document.write( "8, 6, and 3 divide evenly.
\n" ); document.write( "------------------------------
\n" ); document.write( "So you convert each of your give fractions to ones having the lcm as
\n" ); document.write( "its denominator, as follows:
\n" ); document.write( "1/8 = 3/24 (I got that by multiply numerator and denominator by 3.
\n" ); document.write( "5/6 = 20/24 (I multiplied top and bottom by 4)
\n" ); document.write( "2/3 = 16/24 (I multiplied top and bottom by 8)
\n" ); document.write( "---------------
\n" ); document.write( "Now they all have the same denominator so I can add and subtracgt
\n" ); document.write( "the numerators to get:
\n" ); document.write( "[3 + 20 -16]/lcm
\n" ); document.write( "=7/lcm
\n" ); document.write( "=7/24
\n" ); document.write( "---------------
