Answer:
Let the empty place be x. In ( a)
( a ). Then, - 4/7 = x/28
x = - 4 * 28/7 = - 4 * 4 = - 16
x = - 16
( b ). 5 / - 17 = - 15/ x
x = - 15 * ( - 17) / 5 = 51
Now, - 15/ 51 = y / - 85
y = - 85 ( - 15) / 51
y = - 25

Step-by-step explanation:
(a) - 4/7 = x/28
We need to find x.
So by cross multiplication, x=28*(-4/7)
x=-16
(b) 5/-17= -15/x = y/-85
First take 5/-17 = - 15/x
By cross multiplication, x=-15*(-17/5)
x=51
Now, take - 15/51 = y/-85
By cross multiplication, y=(-15/51)*(-85)
y=25
