Answer:
1. Not proportional
2. Proportional
3. Proportional
4. Not proportional
Step-by-step explanation:
A trick I used was to divide 3 by 7 and I got around 0.42.
Then I proceeded to type the fractions into the calculator to see which ones gave me 0.42.
Example: 12 divided by 28 is equal to about 0.42 so it is proportional
24 divided by 54 is not 0.42 so it is not proportional
