A recipe for pancakes calls for 2 cups flour and 1 1/2 cups of milk to make a serving of 4. Ming has plenty of flour, but only 4 cups of milk. how many servings can he make?
Answer provided by our tutors
serving of 4 are made out of :
2 cups of floor
1 1/2 cups of milk = 1.5 cups of milk
we have plenty floor but only 4 cups of milk.
let x be the number of servings of 4 that we can make with 4 cups of milk and x is integer
we have the following proportion
1.5 : 1 = 4 : x
x = 4/1.5
x = 2.67
thus we conclude that we can make pancakes for 2 serving of 4.
