› Amelia is buying walnuts for a recipe. She already has 1 1/4 cups of walnuts. The recipe calls for * 2 3/4 cups of walnuts. How many cups of walnuts does Amelia need to buy?

To find out how many cups of walnuts Amelia needs to buy, we need to subtract the amount she already has from the amount the recipe calls for.

The recipe calls for 2 3/4 cups of walnuts. Amelia already has 1 1/4 cups.

To subtract these two amounts, we need to find a common denominator, which is 4.

1 1/4 = 5/4

2 3/4 = 11/4

Now we can subtract:

11/4 - 5/4 = 6/4

Simplifying the fraction, we have:

6/4 = 1 2/4 = 1 1/2

Amelia needs to buy 1 1/2 cups of walnuts.
