Answer 2

MMC 5,1 = 5

MMC 12,1 = 12

MMC a,1 = 1

MMC 2,4 = 4

2 - 4 / 2
1 - 2 / 2
1 - 1
------------
2 . 2 = 4

MMC 3,6 = 6

3 - 6 / 2
3 - 3 / 3
1 - 1
-----------
2 . 3 = 6

MMC 3,6 = 6

3 - 6 / 2
3 - 3 / 3
1 - 1
-----------
2 . 3 = 6

MMC 2, 4 ,3 = 12

2 - 4 - 3 / 2
1 - 2 - 3 / 2
1 - 1 - 3 /3
1 - 1 - 1
----------------
2 . 2 . 3 = 12

MMC 3,6,9 = 18

3 - 6 - 9 / 2
3 - 3 - 9 / 3
1 - 1 - 3 / 3
1 - 1 - 1
---------------
2 . 3 . 3 = 18

MMC 5,10,20 = 20

5 - 10 - 20 / 2
5 - 5 - 10 / 2
5 - 5 - 5 / 5
1 - 1 - 1
------------------
2 . 2 . 5 = 20
