Mileys chocolate cookie bar recipe calls for 1/2 of a cup of sugar. How much sugar would miley need if she's making 1 1/2 of a batch of cookie bars

To answer this item, we are to use the concept of ratio and proportion. By this, we are to get the ratio of the number of cups of sugar per batch and equate this to the ratio of the second batch. To answer, we let x be the number of the cups of sugar for the second batch.

(1/2 cup of sugar) / 1 = (x cup of sugar) / (1 1/2)

x = 0.75

Hence, the number of cups of sugar needed is equal to 0.75 cups.
