c) ( 7/5 + 3/4 - 3 - 1/ 4 ) : ( 5/6 + 2/15 )
d) ( 7/5 + 3/4 - 3 - 1/ 4 ) : ( 5/6 + 2/15 )- 2/3

Answer 1

Explicación paso a paso:

7/5+3/4-31/4

7/5+3/4-13/4 = - 11/10

5/6+2/15 = 29/30

(7/5+3/4-3-1/4):(5/6+2/15)

(-11/10):(29/30)

- 33/29

(7/3+3/4-3-1/4):(5/6+2/15)-2/3

(-11/10):(29/30)-2/3

(-33/29)-2/3

- 157/87
