Answer 1

A = 176/15

B = 1/19

C = -1

D = - 1/48

E = 80/17

F = - 1/10

Explanation:

A) -4/3 x (-75-13)/10

(-4/3) x (-88/10) = 176/15

B) 4/19 - 12/19 + 9/19 = (4 - 12 +9)/19

= 1/19

C) -6/5- (3/34)/(-15/34)

-6/5 - (-1/5)

-6/5 + 1/5 = -1

D) (3/10) x (5/18) = 15/180 = 1/12

(1/16) - (1/12) = - 1/48

E) (3/32) - (1/32) = 2/32 = 1/16

(5/17) / (1/16) = 80/17

F) (4/20) x (12/8) x (-5/15) = - 240/2400 = - 1/10
