Fat content of a pancake

Question

A pancake that is 4 inches in diameter contains 5 grams of fat.

How many grams of fat are contained in a pancake that is 6 inches in diameter?

Answer 1

For this problem, you need to find how many grams of fat are in each inch of diameter of the pancake. To do this, we divide the 5 grams of fat by the 4 inches of diameter to get 1.25 grams of fat per inch (5/4 =1.25). Then we multiply the 1.25 grams of fat per inch of diameter by the new diameter (6 inches). This gives us our toal grams of fat in a 6 inch pancake (1.25*6 = 7.5 grams of fat)
