PLEASE HELP ME PLEASE!

5/8 cups of vinegar, because if 2 1/2 cups of water are equal to 1 1/4 cups of vinegar, that means that the amount of vinegar you need is half the amount of water you need. So, I made 1 1/4 cup of water in to 1 2/8 which is equal to 1 1/4 cups of water. and than i made 1 1/4 into a improper fraction which would be 10/8 and i divided 10 by 2 which is 5. so the amount of vinegar she needs is 5/8. 5/8 is your answer.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

the correct answer would be:
