Henry thinks he can figure out how high his kite is while flying it in the park. first, he lets out 150 feet of string and ties the string to a rock on the ground. then, he moves from the rock until the string touches the top of his head. he stands up straight, forming a right triangle with the ground. he wants to find out the distance from the ground to his kite. he draws the following diagram to illustrate what he has done.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

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.
