15. Diana and John are making three-cheese

lasagna. The recipe calls for 100 g of

Romano, 300 g of mozzarella, and 250 g

of cottage cheese.

a) Write a ratio in lowest terms to

compare the amounts of the three

cheeses. State the order of the cheeses.

100 g of Ramano : 300 g of mozzarella : 250 g of cottage cheese <---you divide each number by 50

Then you get the ratio of 2 : 6 : 5 .

b) What amounts of Romano and cottage

cheese do you need to make lasagna that

contains 900 g of mozzarella cheese?

Hint: Use equivalent ratios to help you.

You need 300 g of Romano and 750 g of cottage
