Question

Holly stops to drink 5 ounces of water every two miles she

runs. The further that Holly runs, the more she drinks water.
Complete the table by writing two equivalent ratios

Answer 1

the amount of water she drinks is x, the mileage is y:

x y

2 miles 5 oz

4 miles 10 oz

6 miles 15 oz

the ratios would be 4/10 and 6/15

Explanation:

for every 2 miles Holly runs, she drinks 5 oz of water, right? the ratio is 5:2, so if you were to come up with other numbers that match the ratio, they have to be divisible by the parts of the ratio. so if she runs 2 miles, she drinks 5 oz. if she runs 4 miles, then she drinks 10 oz.

think of a ratio like a fraction (in this case it would be 2/5). if you were to make equivalent ratios, then the two fractions would have to be equal, right? well, when you simplify all of the numbers listed in the table above after making them into fractions, they would all go back to 2/5, so the numbers i came up with above are equivalent ratios, meaning they have the same value when simplified.

hopefully that helps and isn't too confusing! if you need other help, let me know! :)
