Sharon wants to make cookies for her class bake sale. She found a recipe that calls for 2/3 cups of flour for each batch of cookies. How many batches can she make using 12 cups of flour?
Answers
Answer:
Since Sharon wants to cookies, and the recipe makes enough for 12,
then he must double the brownie recipe, because 12 × 2 = 24. To double a
number, you can either multiply it by 2 or you can add the number to itself.
Since he wants to make 24 cookies, and the recipe makes enough for 48, then he
must cut the cookie recipe in half, because 48 ÷ 2 = 24.
The most difficult calculation is probably determining the required amount of
flour. You will need to double the amount from the brownie recipe ( 3
4
cup) and
add it to half the amount from the cookie recipe (2 cups). There are many ways
to determine the result of 3
4 × 2 or 3
4 +

. For example, you can use fractions of
geometric shapes such as circles or squares, or use money such as Canadian
quarters. You could also literally use measuring cups with flour, sand, or some
other measurable material.
