Monica’s lemon cookie recipe calls for 3 cups of sugar. How much much to make 4 1/2 Batches of cookies.
Alex

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

The price of an item has dropped to $63 today. Yesterday it was $140. What was the percentage decrease?
den301095 [7]

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:

\text{ Percentage Decrease = }\frac{\text{ Original Price - Present Price}}{\text{ Original Price}}\text{ x 100}

We get,

Original Price = $140

Present Price = $63

\text{ Percentage Decrease = }\frac{\text{ Original Price - Present Price}}{\text{ Original Price}}\text{ x 100}\text{ = }\frac{\text{ 140 - 63}}{\text{ 140}}\text{ X 100}\text{ = }\frac{77}{140}\text{ X 100}\text{ = }0.55\text{ x 100}\text{Percentage Decrease  = }55\text{\%}

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