There is a proportional relationship between your distance from a thunderstorm and the time from when you see the lightning and hear thunder, if there are 9 seconds between lightning and thunder ,the storm is about 3 kilometers away if you double the amount of time between the lightning and thunder, do you think the distance in kilometers also double? justify your reasoning.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
