The Housing Commission of Woodcreek County is interested in finding out more about the number of rental units that do not meet standard living requirements in both Ridge Township and Crystal Township. Units are randomly selected in both cities. Of the 85 units sampled in Ridge Township (call this Township 1), 17 do not meet the requirements. Of the 80 units sampled in Crystal Township (call this Township 2), 24 do not meet the requirements. What is the estimate for the proportion of rental units that do not meet the requirements in Township 1

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
