Step-by-step explanation: when ur doing subtacting  ur gonna notice a pattern like 11.25 10.75 10.25 9.75 9.25 because if u start with 19 and minus 0.50 the u get ur answers 16 the 11.25 dosnt count because that for the gift after u spend 7.24 on the gift ur gonna have 11.25 and keep couniting down but also keep tract on how many it takes to get to 2.75

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
