Molly has 9 cups of flour. If this is 3/4 of the number she needs to make bread, how many cups does she need?

12

Step-by-step explanation:

Since we know that 9 is 3/4 of what she needs you would divide 9 by 3 so we know how much 1/4 of a cup is worth.

(9/3=3) now we know she needs 3 cups of flour for 1/4 of the expression. Now we multiply 3 by 4 so we can get the answer.

(3x4=12)

Molly needs 12 cups of flour to make bread.

Hope this helps :)
