If a recipe calls for 4 1/2 cups of flour for 48 cookies, how
much flour would be needed for 24 cookies?

2 1/4 cups

Step-by-step explanation:

Since we want half as many cookies as the recipe can make, we just half the amount of ingredients used.

Originally, we have 4 1/2 cups of flour for 48 cookies. However, for 24 cookies, which is half of 48, we want to have half of 4 1/2: (4 1/2)/2 = 2 1/4 cups.

Thus, the answer is 2 1/4 cups of flour.

Hope this helps!

2 ¼ cups

Step-by-step explanation:

24 is ½(48)

Flour needed:

½(4 ½)

2 ¼

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
