How many more cups of flour does Jana need?
Responses
A. 4 1/2 cups
B. 4 1/8
C. 11 5/8
D. 4 cups
To find out how much more flour Jana needs, we need to add the amount of flour needed for the pie crust and cookies and subtract it from the amount of flour she already has.
The total amount of flour needed is 5 1/4 + 2 5/8 = 15/4 + 21/8 = 30/8 + 21/8 = 51/8 cups.
Subtracting the amount of flour Jana already has (3 3/4 cups) from the total amount needed (51/8 cups) gives us: 51/8 - 15/8 = 36/8 = 9/2 = 4 1/2 cups.
Therefore, Jana needs 4 1/2 additional cups of flour. The correct answer is A. 4 1/2 cups.
To find out how many more cups of flour Jana needs, we need to add the amount of flour needed for pie crusts and cookies, and then subtract the amount of flour she already has.
The sum of 5 1/4 cups and 2 5/8 cups is:
5 1/4 + 2 5/8 = 21/4 + 21/8 = 42/8 + 21/8 = 63/8
Jana has 3 3/4 cups of flour, so we will subtract that from the total needed:
63/8 - 15/4 = 63/8 - 30/8 = 33/8
Therefore, Jana still needs 33/8 cups of flour. This is equivalent to 4 1/8 cups of flour.
The correct answer is B. 4 1/8.
To find out how many more cups of flour Jana needs, we need to subtract the amount of flour she already has from the total amount of flour needed for both the pie crusts and cookies.
First, let's add up the amounts of flour needed for the pie crusts and cookies:
5 1/4 cups + 2 5/8 cups
To make addition easier, we need to find a common denominator:
The common denominator of 4 and 8 is 8.
Converting 5 1/4 cups to eighths:
(5 * 8)/4 + 1/4 = 40/8 + 1/8 = 41/8
Converting 2 5/8 cups to eighths:
(2 * 8)/8 + 5/8 = 16/8 + 5/8 = 21/8
Now, let's add the fractions:
41/8 + 21/8 = 62/8
Next, we need to subtract the amount of flour Jana already has from the total amount needed:
62/8 - 3 3/4 cups
To make subtraction easier, we need to find a common denominator:
The common denominator of 4 and 8 is 8.
Converting 3 3/4 cups to eighths:
(3 * 8)/4 + 3/4 = 24/8 + 3/8 = 27/8
Now, let's subtract the fractions:
62/8 - 27/8 = 35/8
Converting 35/8 back to a mixed number:
35 รท 8 = 4 with a remainder of 3
So, the answer is 4 3/8 cups.
