Sue need 1 1/4 cups of flour for a batch of cookies. how many batches can she make with 9 cups of flowers? a. 6 batches b. 8 batches c. 7 batches d. 4 batches

4 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 4 4/4 = 5

6 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 6 6/4 = 7 1/2

7 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 7 7/4 = 8 3/4

8 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 8 8/4 = 10

The answer is C because 8 batches needs 10 cups of flour, and 7 batches is closest to 9 cups than 6 batches.

You can also look at it like this:

1 1/4c ≤ 9 (c is # of cups)

Or you could have multiplied 4, 6, 7, 8 to 1 1/4 or 1.25

it would be 6xy and -16xy.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
