Two friends, Andrew and Liz, are playing a game using this spinner. If the spinner lands on region 4, Andrew wins. If it lands on region 1, Liz wins. If it lands on any other region, nobody wins. Is this a fair game?

The answer is B both players have 1/4 of chance of winning so it is a fair game

Step-by-step explanation:

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

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
