It takes 1 1/2 cups of flour, 1 1/4 cups of sugar, and 1/2 cup of butter to bake fifteen shortbread cookies. if ramon has 5 cups of flour, 4 cups of sugar, and 1 3/4 cups of butter, how many shortbread cookies can he bake?

5 cups of flour will make 5/(1 1/2) x 15 = 50 shortbread cookies
4 cups of sugar will make 4/(1 1/4) x 15 = 48 shortbread cookies
1 3/4 cups of butter will make (1 3/4)/(1/2) x 15 = 52 1/2 shortbread cookies

Therefore, 5 cups of flour, 4 cups of sugar, and 1 3/4 cups of butter will make 48 shortbread cookies.
