Question

Mrs. Appler used 1/2 gallon of olive oil to make 8 identical batches of salad dressing.

a. How many gallons of olive oil did she use in each batch of salad dressing?
b. How many cups of olive oil did she use in each batch of salad dressing?

Answer 1

a) 1/16 gallon

b) 1/8 cups

Explanation:

given data:

Total quantity of olive oil = 1/2 gallon

Total number of salad dressing is 8

a) Total quantity olive oil for 8 identical salad dressing = 1/2 gallon

therefore for each salad dressing she would need
`= ((1)/(2))/(8)= (1)/(16)` gallon olive oil

b) suppose for 1/2 gallon oil one one cup is used

therefore for 1/16 gallon total cups of olive oil used is 1/8 cups would need

Answer 2

a. She used
`(1)/(16)\ gal` of olive oil in each batch of salad dressing.

b. She used
`1\ cup` of olive oil did she use in each batch of salad dressing.

Explanation:

You know that she made 8 identical batches of salad dressing.

Then:

a. Since she used
`(1)/(2)\ gal` of olive oil to make them, you must divide
`(1)/(2)\ gal` by 8 in order to calculate the amount of gallons of olive oil she used in each batch of salad dressing.

Therefore, you get:

`(1)/(2)\ gal/8=(1)/(16)\ gal`

So, she used
`(1)/(16)\ gal` of olive oil in each batch of salad dressing.

b. Now, you need to remember that:

`1\ gal=16\ cups`

Knowing that, you can make the conversiom from gallons to cups:

`((1)/(16)\ gal)((16\ cups)/(1\ gal))=1\ cup`

Therefore, she used
`1\ cup` of olive oil did she use in each batch of salad dressing.
