Which of the following is an example of a ratio? number of dogs who like good boy treats number of chocolates per bag number of people who like math all of the above

all of them

Step-by-step explanation:

dogs per Good Boy treats Probably this would work better the other way around.

good boy treats / dog

Both could be considered correct.

If you have a sticky teacher and D is not correct, you could try B
