Answer:
1 1/2 cups flour. 1 1/3 cup oats. 4/9 cup oats.
Step-by-step explanation:
For every 3/4 cup of flour there is 2/3 cup of oats. So if you have 2/3 cup of oats you would have 3/4+3/4 cups of flour or 1 1/2 cups of flour. If you have 3 cups flour you would have 2/3+2/3 cup oats. Find the last amount by multiplying 1 by 1/3 then dividing by 3/4.
