Rose divided two cups of dog food among her three dogs. how much dog food did each dog get?
how many 1/8 pound packages of mint can sam make from 3/4 pound of mint?

For this equations you would continue to break down the fractions as so: 3/4 divided by 1/8 = 6 but to double check this here are steps:
 1st you take: 3/4 divided by 3 is 3/12, simplified to 1/4
then you take 3/4 which can be 1/4 for each dog so you need 1/8 for each dog so you double it because 1/4 plus 1/4 equal 1/8 so each dog gets two 1/8 scoops which is 
1/8 times 2 = 1/4 for each dog and three dogs so they still get 1/4 pound each.
so total of 1/8 x 6 = 3/4
so 6 1/8 servings.

21 is the answer the answer is 21
