Question

Julie is using this recipe to make salad dressing. The recipe makes 1 batch of dressing. She plans to make 3 batches of the dressing. She has 4 cups of vegetable oil. Write a multiplication expression to show how much vegetable oil is needed for 5 batches.

Answer 1

Answer: There is
`6(2)/(3)\ cups` needed for 5 batches.

Explanation:

Since we have given that

Number of batches of the dressing she plans = 3

Number of vegetable oil she needed for this = 4 cups

We need to find the number of cups of vegetable oil is needed for 5 batches.

For this we will use "Unitary Method" :

For 3 batches of dressing, Number of cups of vegetable oil = 4

For 1 batch of dressing, Number of cups of vegetable oil is given by

`(4)/(3)`

For 5 batches of dressing, Number of cups of vegetable oil is given by

`(4)/(3)* 5\\\\=(20)/(3)\\\\=6(2)/(3)\ cups`

Hence, there is
`6(2)/(3)\ cups` needed for 5 batches.
