Yolanda has 4 1/4 cups of flour. She needs 1 2/3 cups of flour to make a batch of cookies. How many cookies can Yolanda make with the flour she has?
To find out how many cookies Yolanda can make with the flour she has, we need to divide the total amount of flour she has by the amount of flour needed per batch of cookies.
Yolanda has 4 1/4 cups of flour, which can be expressed as a mixed number: 4 + 1/4 = 17/4 cups of flour.
Yolanda needs 1 2/3 cups of flour to make a batch of cookies, which can also be expressed as a mixed number: 1 + 2/3 = 5/3 cups of flour.
Now, we divide the total amount of flour Yolanda has by the amount of flour needed per batch of cookies:
17/4 ÷ 5/3
To divide fractions, we multiply the first fraction (17/4) by the reciprocal of the second fraction (3/5):
(17/4) × (3/5)
To multiply fractions, multiply the numerators and then the denominators:
(17 × 3) / (4 × 5) = 51/20
Therefore, Yolanda can make 51/20 batches of cookies.
Since a batch is a whole number, we need to simplify the fraction.
To simplify 51/20, we can divide both the numerator and denominator by their greatest common divisor, which is 1:
(51 ÷ 1) / (20 ÷ 1) = 51/20
So, Yolanda can make 51/20 batches of cookies, which is equivalent to 2 11/20 batches.
no idea. How many cookies in a batch?
However, she can make (4 1/4) ÷ (1 2/3) batches
