Respuesta:

a. -49/120

b. -7/36

c. 34/75

d. 5/12

Explicación paso a paso:

a. [(2/3 - 1/2 x 4/15) - (2/10+3/5) : (2/3 + 4/9)] : (3/5x10/7 - 2/5) =

[(2/3 - 2/15) - (4/5) : (10/9)] : (6/7 - 2/5) =

[8/15 - 18/25] : 16/35 = -14/75 : 16/35

-14/75 x 35/16 = -49/120

b. [(2/3 + 1/2 x 4/15) - (2/10+3/5) x (2/3 + 4/9)] : (3/5x10/7 - 2/5) =

[(2/3 + 2/15) - 4/5 x 10/9] : (6/7 - 2/5)

[4/5 - 8/9] : 16/35 = -4/45 : 16/35 = -4/45 x 35/16 =

-7/36

c. 11/6 : 5/2 - 7/25 = 11/15 - 7/25 = 55/75 - 21/75 = 34/75

d. 3/8 - 5/6 : 4/3 + 2/9 x 27/9 = 3/8 - 5/8 + 2/3 =

9/24 - 15/24 + 16/24 = 5/12
