Madison has one half cup of olive oil she used 1/6 cup. how much is left?

1 / 2 is same as 3 / 6

1 / 2 - 1 / 6 = 3 / 6 - 1 / 6 = 2 / 6 =

2 • 1 / 2 • 3 = 1 / 3

1 / 3 cup is left

To find out how much olive oil is left, we need to subtract the amount used from the initial amount.

Initial amount of olive oil: 1/2 cup
Amount used: 1/6 cup

To subtract fractions, the denominators must be the same. Thus, we need to have both fractions with a common denominator.

The common denominator for 2 and 6 is 6. Therefore, we can write 1/2 as 3/6.

Now, subtract the amount used from the initial amount:

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

The simplified form of 2/6 is 1/3.

Therefore, Madison has 1/3 cup of olive oil remaining.
