Question

A potato chips manufacturing facility uses 1/6 of a barrel of oil in each batch. The facility used 2/3 of a barrel of oil yesterday. How many batches of potato chips did the facility make? A. 2/3 B. 1/4 C.2 D.4

Answer 1

The answer is D. 2/3 = 4/6 4/6 divided by 1/6 = 4

Answer 2

Option D. 4 batches

Explanation:

A potato chips manufacturing facility uses 1/6 barrel of oil in each batch and we have to find the batches of potato chips manufactured in 2/3 of a barrel.

We will use unitary method to solve this question.

∵
`(1)/(6)` barrel is required to manufacture batch = 1

∴ 1 barrel is required to manufacture batches = 1 ÷
`(1)/(6)`

∴
`(2)/(3)` barrel is required to manufacture batches =
`((1)/((1)/(6)))((2)/(3))=((6)/(1))((2)/(3))=6.(2)/(3)=4`

Therefore Option D.4 is the correct option.
