The local farmer market sells two pound bags of apples that contain eight apples. what two unit rates can be found to represent the ratio, do they make sense why.

2:8

1:4

8:2

1:1/4

1:.25

there are two unit rates that could make sense: 1:4, because, using the ratio of 2:8, you divide 2 by 2, and 8 by 2, therefore making it equivalent, and 1: 0.25, or 1: 1/4, because you switch the ratio into 8:2 instead of 2:8, and divide each by 4. The first ratio makes more sense, because of the order, and how it doesn't need a fraction or decimal, but both could work.

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
