For one batch of cookies, the ratio of ounces of butter to ounces of flour is 2 to 3. How many ounces of butter and ounces of flour are needed for 3 batches?

Answer 1

For one batch of cookies, if the ratio of butter to flour is 2 to 3, then for 3 batches, the ratio of butter to flour remains the same.

The total ratio of butter to flour for 3 batches is therefore 2 to 3.

If the ratio is 2 to 3, for every 2 ounces of butter, there are 3 ounces of flour.

Since we want to know the total amount of butter and flour for 3 batches, we multiply the ratio by the number of batches:

2 ounces of butter x 3 batches = <<2*3=6>>6 ounces of butter
3 ounces of flour x 3 batches = <<3*3=9>>9 ounces of flour

Therefore, for 3 batches of cookies, 6 ounces of butter and 9 ounces of flour are needed.
