1/3 cup of flour makes 5 dinner rolls. How many cups of flour for 3 dozens rolls?
36/5 = 7 1/5
(1/3) * (36/5) = 36/15 = 2 6/15 = 2 2/5 cups
To find out how many cups of flour are needed for 3 dozens of rolls, we can use the following steps:
Step 1: Determine the number of dinner rolls in 3 dozens.
There are 12 rolls in one dozen, so for 3 dozens, we have 3 x 12 = 36 dinner rolls.
Step 2: Calculate the amount of flour needed for one dinner roll.
If 1/3 cup of flour makes 5 dinner rolls, then 1 dinner roll requires 1/3 cup divided by 5.
1/3 cup ÷ 5 = 1/15 cup of flour.
Step 3: Calculate the total amount of flour needed for 36 dinner rolls.
Now that we know one dinner roll requires 1/15 cup of flour, we can multiply this amount by the number of dinner rolls.
1/15 cup × 36 = 36/15 cups.
Step 4: Simplify the fraction (if necessary).
To simplify 36/15, we can divide both the numerator and denominator by 3.
36 ÷ 3 = 12, and 15 ÷ 3 = 5, so the fraction simplifies to 12/5.
Therefore, you would need 12/5 cups of flour for 3 dozens (36) dinner rolls.
To find out how many cups of flour are needed for 3 dozen dinner rolls, we'll need to first determine how many rolls are in 3 dozen.
Since 1 dozen is equal to 12, multiplying 12 by 3 gives us a total of 36 rolls (3 x 12 = 36).
Now, to calculate the amount of flour needed, we can use the given information that 1/3 cup of flour makes 5 dinner rolls.
First, we'll find out how many sets of 5 dinner rolls are in 36 rolls. We can do this by dividing 36 by 5:
36 / 5 = 7 remainder 1
This means that we will have 7 sets of 5 dinner rolls (35 dinner rolls) and 1 additional dinner roll.
To determine the amount of flour needed for 35 dinner rolls, we'll multiply 35 by 1/3:
35 * 1/3 = 35/3 = 11 and 2/3 cups of flour
So, for 3 dozen dinner rolls (or 36 rolls), you will need approximately 11 and 2/3 cups of flour.
