Question

Timmy surveyed 60 dentists and found that 48 favored the use of fluoride toothpaste. How do you write a ratio to compare the number of dentists who don't favor using fiuoride to those who do?

Answer 1

See a solution process below:

Explanation:

If `48` out of `60` dentists favored using fluoride toothpaste,

Then: `60 - 48` or `12` out of `60` dentists did not favor using fluoride toothpaste.

Therefore, the ration for dentists who don't favor using fluoride to those who do is:

`12:48` or `1:4`
