Method 2 Greatest Common Divisor To reduce a fraction to lowest terms (also called its simplest form), just divide both the numerator and denominator by the GCD (Greatest Common Divisor) For example, 3/4 is in lowest form, but 6/8 is not in lowest form (the GCD of 6 and 8 is 2) and 6/8 can be written as 3/42) multiply the denominator of fraction 1 by the numerator of the fraction 2 This process is called crossmultiplication Here are some examples 1/2 is equivalent to 14/28 because 1 x 28 = 2 x 14 = 28;2 Atomic Weight 2 He 400 3 Li 694 4 Be 901 5 B 1081 6 C 11 7 N 1401 8 O 1600 9 F 1900 10 Ne 18 11 Na 2299 12 Mg 2431 3B 13 Al 2698 14 Si 2809 15 P 3097 16 S 37 17 Cl 3545 18 Ar 3995 19 K 3910 Ca 4008 21 Sc 4496 22 Ti 4787 23
