Answer 1

a) (-5/8)*16= (-5/8) * 16/10 = -1b) 1 1/2 * (-2/3)= 3/2 * (-2/3) = -1c) (-5 2/3) : (-2 5/6)= (-17/3) * (-6/17) = -2d) (-1) : 2 1/2= -2 1/2e) 3 1/3 : (-2 2/9)=  10/3 8 (-9/20) = -1 1/2

f) (-5 1/3) : (- 8/11)= (16/3) * (-11/8) = (-2/3) * (-11) =  - 22/3 = -7 1/3

Answer 2

A)  =-5/8 * 16/10 = -2/2 = 1
b) = 3/2 * -2/3= -1/1= -1
c) = -17/3 * -6/17 = 2/1 = 2
d) = (-1) : 5/2 = (-1) * 2/5 = -2/5
e) = 10/3 : -20/9 = 10/3 * -9/20 = -3/2
f) = 16/3 * 11/8 = 22/3
