Answer: 90 g of butter
================================================
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
