Question

A recipe calls for 1 ¾ cups sugar for 24 cookies. How many cups of sugar would you need for 30 cookies?

Answer 1

You're going to increase every component by a factor 30/24, which is 5/4.

Sugar requirement 1¾ is 7/4; multiplied by 5/4, it becomes 35/16 which is the mixed number two and 3/16.
