Question

Margot has 21 1/2 pounds of flour 8 pounds of butter and 18 1/2 ponds of sugar to make shortbread cookies if she makes 12 batches of cookies and uses all the ingredients how many pounds of ingredients are used in each batch

Answer 1

4 pounds of ingredients are used in each batch.

Explanation:

Amount of flour =
`21(1)/(2)pounds = (43)/(2)pounds`

Amount of butter = 8 pounds

Amount of sugar =
`18(1)/(2)pounds= (37)/(2) pounds`

So, the total amount of all ingredients will be:
`((43)/(2)+(37)/(2)+8)pounds = ((43+37+16)/(2)) pounds= (96)/(2) pounds = 48 pounds`

Given that, she makes 12 batches of cookies using all the ingredients.

Thus, the amount of ingredients used in each batch
`=(48)/(12) pounds = 4 pounds`
