Question

If 8 out of 10 dentists approve a certain brand of toothpaste, what is the ratio of dentist who approve the toothpaste to those who do not, given in simplified form?

Answer 1

That would be 8:2

Simplest form is 4:1.

Answer 2

4:1 since 8 dentists approve and 2 do not, and 8:2 can be simplified by dividing out 2 to get 4:1.
