a)

125, 45

125,45/3

125,15/3

125, 5/5

25, 1/5

5,1/5

1,1

mmc= 3² * 5³ ou 9 * 125 =1 125 >>>>>

b)

48,45

48,45/2

24,45/2

12,45/2

6,45/2

3, 45/3

1,15/3

1, 5/5

1,1

mmc =2^4 *3² * 5 = 16 *9 * 5 =720 >>>>

c)

54,20

54, 20 /2

27,10/2

27, 5/3

9, 5/3

3, 5/3

1, 5/5

1, 1

mmc= 2² * 3³ * 5 = 4 * 27 * 5 =540 >>>>>

d)

66,22

mmc =66

ele é divisivel por 22 e por ele mesmo

e)

25,85/5

5, 17 /5

1, 17/17

1, 1

mmc= 5² * 17 = 25 * 17 =425 >>>>

f )

44,12

44, 12/ 2

22, 6 /2

11, 3/3

11,1/11

9, 1, 3/3

3,1, 1 /3

1, 1, 1

2²* 3^4 = 4 * 81= 324 >>>>

i )

99,22

99,22 / 2

99,11 / 3

33, 11/3

11, 11 / 11

1, 1

mmc = 2 * 3² * 11 = 2 * 9 * 11 =198 >>>>
