Question

simplifique as frções usando o M.D.C 12/42 20/32 15/30 800/100 18/24 14/7 66/99 81/27

Answer 1

12/42   mdc = 6 :  12/6  / 42/6  = 2/7

20/32   mdc = 4:   20/4  / 32/4 = 5/8

15/30   mdc = 15   15/15  / 30/15 = 1/2

800/100 mdc = 100    800/100  / 100/100 = 8/1 = 8

18/24     mdc = 6       18/6  / 24/6 = 3/4

14/7      mdc = 7     14/7  / 7/7 = 2/1 = 2

66/99   mdc = 33    66/33  / 99/33 = 2/3

81/27   mdc = 27    81/27  / 27/27 = 3/1 = 3

Bons estudos
