Question

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

Answer 1

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.
