C. 5/8 + 7/8 + 9/4=
D. 5/6 Dividido en 6/9

Answer 1

Respuesta:

a) 7/9

b) 17/15

c) 15/4

d) 15/12

Explicación paso a paso:

a) 1/3 * ( 3/2 + 5/6 ) = 7/9

= 1/3 * 14/6  

C. A.

3/2 = 9/6

9/6 + 5/6 = 14/6

1 * 14 = 14

3 * 6 = 18

1/ 3 * 14/6 = 14/18 = (simplificado) 7/9

b) ( 3/5 + 6/5 ) - 2/3 = 17/15

= 9/5 - 2/3

= 27/15 - 10/15

C. A.

mcm entre 5 y 3 = 15

9 * 3 = 27

2* 5 = 10

27/15 - 10/15 = 17/15

c) 5/8 + 7/8 + 9/4 =

= 5/8 + 7/8 + 18/8

C. A.

mcm entre 8 y 4 = 8

9 * 2 = 18

5/8 + 7/8 + 18/8 = 30/8 = (simplificado) 15/4

d) 5/6 : 6/9 =

= 5/6 * 9/6

C. A.

5 * 9 = 45

6 * 6 = 36

5/6 * 9/6 = 45/36 = (simplificado) 15/12
