i need help Samir needs 450g of butter to make 60 shortbread biscuits. How many will he use to make 12 biscuits?

Work Shown:

450 g of butter = 60 biscuits

450/60 g of butter = 60/60 biscuits ... divide both sides by 60

7.5 g of butter = 1 biscuit

This means each biscuit needs 7.5 grams of butter

Multiply both sides by 12 to get

7.5 g of butter = 1 biscuit

12*7.5 g of butter = 12*1 biscuit

90 g of butter = 12 biscuits
