Deviation
Alice, Raul, and Maria are baking cookies together. They need 3/4 cup of flour and 1/3 cup of butter to
make a batch of cookies. They each brought the ingredients they had at home.
Alice brought 2 cups of flour and 1/4 cup of butter
Raul brought 1 cup of flour and 1/2 cup of butter
1
Maria brought 14 cups of flour and 3/4 cup of butter
If the students have plenty of the other ingredients they need (sugar, salt, baking soda, etc.), how
many whole batches of cookies can they make?
Step 1 – Find the total amount of flour that the three friends brought.
Step 2- Find the total amount of butter that the three friends brought.
Step 3 – Divide the total butter that the friends have by the amount of butter you need for each batch of
cookies.
Step 4 – Divide the total amount of flour that the friends have by the amount of flour that you need for each
batch of cookies.
Step 5 – Determine how many total batches you can make. Remember, you need to have enough butter AND
flour.
