Ayuda porfavor

Answer 1

Respuesta:

3/6 + 2/5 = 9/10

(Mínimo Común múltiplo)

6   5  (mitad)=2

3   5  (tercera)=3

1    5  (quinta)=5

2*3*5= 30

3/6 * 5/5 = 15/30

2/5 * 6/6 = 12/30

15/30 + 12/30

= 27/30

=9/10

8/6  -7/8 = 11/24

MCM

6   8 =2

3   4 =2

3   2 =2

3   1 =3

1

2*2*2*3 =24

8/6 * 4/4 = 32/24

7/8 * 3/3 = 21/24

32/24 - 21/24

=11/24

1/5 + 1/3 = 8/15

MCM

5   3 =3

5   1 =5

1

3*5=15

1/5 * 3/3 = 3/15

1/3 * 5/5 = 5/15

3/15 + 5/15

= 8/15

2/9 + 3/2 = 31/18

MCM

9   2 =2

9   1 =3

3     =3

1

2*3*3=18

2/9 * 2/2 = 4/18

3/2 * 9/9 = 27/18

4/18 + 27/18

= 31/18

3/4 - 1/5 = 11/20

MCM

4   5 =2

2   5 =2

1    5 =5

    1

2*2*5 = 20

3/4 * 5/5 = 15/20

1/5 * 4/4 = 4/20

15/20 - 4/20

= 11/20

6/9 - 1/3 = 1/3

MCM

9    3 =3

3    1 =3

1

3*3 = 9

6/9 * 1/1 = 6/9

1/3 * 3/3 = 3/9

6/9 - 3/9

=3/9

=1/3

espero te sirva y que tengas buen día
