Let U be the set of whole numbers from 5-10 inclusive. Set A={5, 7, 9}, Set B = {5, 8, 10}. AUB<

AUB=(5,7,8,9,10)

Step-by-step explanation:

A=(5,7,9)

B=(5,8,10)

AUB=(5,7,8,9,10)

uhhh idk u yolo?

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.
