How much more of a cup of chopped
walnuts do you need? All your walnuts
are the same size. How many more
walnuts should you chop? Explain.

Answer 1

If you already chopped 4 walnuts and you have only gotten 1/4 cup of the chopped walnuts, it means that each walnut yields 1/4 cup / 4 walnuts = 1/16 cup of chopped walnuts.

To find out how much more chopped walnuts you need, we can subtract the amount you have from the total amount the recipe calls for:

1 cup - 1/4 cup = 3/4 cup

So you need 3/4 cup of chopped walnuts more.

To find out how many more walnuts you should chop, divide the amount you need by the amount each walnut yields:

3/4 cup / (1/16 cup/walnut) = 12 walnuts

So you should chop 12 more walnuts to get the desired amount.
