Question

Nora needs 5 and 1/2 cups of flour for a cookie recipe she is making for a large party. So far she has scooped 1 1/2 cups and 1 3/4 cups of flour into her bowl. How many more cups of flour does she need?

Answer 1

Nora still needs 9/4 cups of flour.

Step-by-step explanation:

To find out how many more cups of flour Nora needs, we need to subtract the amount of flour she has already scooped from the total amount of flour she needs.

Let's convert the mixed numbers to improper fractions for easier calculation.

1 1/2 cups can be written as 3/2 cups and 1 3/4 cups can be written as 7/4 cups.

Now, subtract the amount of flour she has already scooped from the total amount she needs: 5 1/2 cups - 3/2 cups - 7/4 cups = 11/2 cups - 3/2 cups - 7/4 cups.

To subtract fractions, we need a common denominator.

The common denominator for 2 and 4 is 4, so we can convert 3/2 cups to 6/4 cups and 11/2 cups to 22/4 cups.

Now, subtract the fractions: 22/4 cups - 6/4 cups - 7/4 cups = 9/4 cups.

So, Nora still needs 9/4 cups of flour.
