Katy has 1 3/8 cups of flour. Her cookie recipe calls for 2 cups of flour. How many more cups of flour does she need for the recipe?

Subtract the amount you have from the amount you need:

2 cups - 1 3/8 cups

Subtract the whole cup first:

2 cups -1 cup = 1 cup

8/8 = 1

Rewrite 1 as 8/8 then subtract the 3/8 you have:

8/8 - 3/8 = 5/8

You need 5/8 cup more

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

15% chance.
