Question

If I need 1/2 cup of oil but I only have 1/3 cup of oil how much oil do I need

Answer 1

We need 1/2 cup of oil and we are told that we already have 1/3 cup of oil, to find out how much we need we subtract this and the result will be the amount of oil we need.

`(1)/(2)-(1)/(3)=(3-2)/(6)=(1)/(6)`

In conclusion, the answer is 1/3 cup of oil
