Mrs. Nava needs 9 1/2 quarts of ice cream to make a dessert to be served at her daughter's birthday party. The flavor of ice cream that Mrs. Nava needs only comes in I-gallon containers. How many I-gallon containers of ice cream will Mrs. Nava need to purchase in order to have at least 9 1/2 quarts of ice cream and as little left over as possible?

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

35 is an outlier
