I have 3 lessons for homework and this problem takes time so?

A)

m.

C. m (5, 6) = 5·2·3 = 30

5|5 6|2

1| 3|3 1|

30 : 5 = 6 = 6·2 = 12 30 : 6 = 5 = 5·1 = 5

12 / 30 - 5 / 30 = 7 / 30

B)

m.

C. m (7, 14) = 7·2 = 14

7|7 14|2

1| 7|

1|

14 : 7 = 2 = 2·3 = 6

14 : 14 = 1 = 1·7 = 7

6 / 14 - 7 / 14 = - 1 / 14

C)

m.

C. m (8, 3) = 2³·3 = = 2·2·2·3 = 24

8|2 3|3

4|2 1|

2|2

1|

24 : 8 = 3 = 3·5 = 15

24 : 3 = 8 = 8·2 = 16

15 / 24 - 16 / 24 = - 1 / 24

Espero haberte ayudado.
