Question

jasmine buys 21 cans of dog food. She gives 1/3 of the cans to her neighbor and she keeps the rest of the cans for her puppy. Jasmines's puppy eats 4/7 of a can of food each day. How many days supply of dog food does jasmine have for her puppy?

Answer 1

21 cans of dog food.

She gives 21/3, or 7 cans to her neighbor.

She now has 21 - 7, or 14 cans for her puppy.

Her puppy eats 4/7 cans a day.

$14 \times \frac{4}{7} =2\times 4= \boxed{\bf{8}}$

Jasmine has 8 days supply of dog food for her puppy.
