Answer 1

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

Answer 2

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
