Answer 1

Olá...

Calcule mentalmente :

a) MMC (2,4)

2, 4 | 2

1, 2 | 2

1, 1

MMC = 2 . 2 = 4

b) MMC (7,5 )

7, 5 | 5

7, 1 | 7

1, 1

MMC = 5 . 7 = 35

c)MMC (9,1 )

9, 1 | 3

3, 1 | 3

1, 1

MMC = 3 . 3 = 9

d)MMC (8,9)

8, 9 | 2

4, 9 | 2

2, 9 | 2

1, 9 | 3

1, 3 | 3

1, 1

MMC = 2 . 2 . 2 . 3 . 3 = 72

e) MMC (3,6,9)

3, 6, 9 | 2

3, 3, 9 | 3

1, 1, 3 | 3

1, 1, 1

MMC = 2 . 3 . 3 = 18

f) MMC (2,4, 6)​

2, 4, 6 | 2

1, 2, 3 | 2

1, 1, 3 | 3

1, 1, 1

MMC = 2 . 2 . 3 = 12

Bons estudos.
