Answer:
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
