Answer: 13 & 1/2 cups of sugar
Whole part = 13
Fractional part = 1/2
===================================================
Explanation:
4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5
1 batch = 3 cups sugar
4.5*(1 batch) = 4.5*(3 cups sugar)
4.5 batches = 13.5 cups of sugar
The decimal number 13.5 converts to the mixed number 13 & 1/2 which is the same as writing 13 1/2
Given:
a.) The price of an item has dropped to $63 today.
b.) Yesterday it was $140.
For us to be able to determine the percentage decrease, we will be using the following formula:

We get,
Original Price = $140
Present Price = $63





Therefore, the decrease of the price in percentage is 55%.
