Betty makes pies. to make 6 pies, she uses 7 1\2 cups of flour. How many cups of flour are needed to make one pie.

(7 1/2) / 6

(15/2) * (1/6) = 15/12 = 5/4 = 1 1/4

7 1/2 divided by 6, if you convert your mixed fraction to entire you have

15/2 divided by 6
...

To find out how many cups of flour are needed to make one pie, you can divide the total amount of flour used for 6 pies by 6.

7 1/2 cups ÷ 6 = 1 1/4 cups

Therefore, Betty needs 1 1/4 cups of flour to make one pie.

To find out how many cups of flour are needed to make one pie, we can divide the total cups of flour used to make 6 pies by the number of pies.

In this case, Betty uses 7 1/2 cups of flour to make 6 pies. So, we need to divide 7 1/2 by 6.

To divide fractions, we multiply the first fraction by the reciprocal (or flipped fraction) of the second fraction.

The reciprocal of 6 is 1/6.

So, the calculation will be:

7 1/2 ÷ 6 = (7 1/2) * (1/6)

First, we convert the mixed number 7 1/2 into an improper fraction:

7 1/2 = (2 * 7 + 1) / 2 = 15/2

Now, we can multiply the fractions:

(15/2) * (1/6) = 15/12

To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 3:

15/12 = (15/3) / (12/3) = 5/4

Therefore, Betty needs 5/4 (or 1 1/4) cups of flour to make one pie.
