the number of cups of flour varies directly as the number of rolls made four cups of flour are needed to make 24 rolls how much flower is needed for 36 rolls
24 / 4 = 6
1 cup of flour makes 6 rolls
24
To solve this problem, we can set up a proportion using the given information. Since the number of cups of flour varies directly as the number of rolls, we know that there is a constant ratio between the two. Let's call this ratio "k."
According to the given information, when 24 rolls are made, 4 cups of flour are needed. So we can set up our proportion like this:
4 cups of flour / 24 rolls = k
To find the value of "k," we divide 4 by 24:
k = 4 / 24 = 1/6
Now that we have the value of "k", we can use it to solve the second part of the question. The question asks for the amount of flour needed for 36 rolls. Let's call this "x" cups of flour.
1/6 cups of flour / 24 rolls = x cups of flour / 36 rolls
To solve for "x", we can cross-multiply and then solve for "x":
24 * x = (1/6) * 36
24x = 6
x = 6 / 24
x = 1/4
Therefore, 1/4 cup of flour is needed to make 36 rolls.
