Kaelyn's mother, Judy, looks after Kaelyn's four-year-old twins so Kaelyn can go to work (she drops off and picks up the twins from Judy's home every day). Since Judy is a relative, Kaelyn made sure, for tax purposes, to pay her mother the going rate for child care ($16,300 for the year). What is the amount of Kaelyn's child and dependent care credit in 2021 if her AGI for the year was $130,000?

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
