Answer 1

A) (4,5,4, M.M.C)
4,5,4 | 2
2,5,2 | 2
1,5,1 | 5
1,1,1 | / 20

2/20+3/20=5/20×6/20=30/20

B) (3,6,4 M.M.C)
3,6,4 | 2
3,6,2 | 2
3,6,1 | 3
1,3,1 | 3
1,1,1 | / 36

5/36×2/36=10/36+9/36=19/36

C) (8,8,10 M.M.C)
8,8,10 | 2
4,4,5 | 2
2,2,5 | 2
1,1,5 | 5
1,1,1 | / 40

4/40×4/40=16/40+2/40=18/40

D) (6,3,4 M.M.C)
6,3,4 | 2
3,3,2 | 2
3,3,1 | 3
1,1,1 | /12

3/12×10/12=30/12-5/12=25/12

PRONTO :)
