please can u help me for my homework thanks a lot the question is below..

A container is 1/3 full of water and 1/4 full of oil. What fraction of the container is empty?

You need to add 1/3 and 1/4. What is the common denominator?

I don't know the answer either! its also for my math homework! can someone please give the answer?

Of course! I can help you with that. To find the fraction of the container that is empty, we need to subtract the fractions that represent the water and oil from 1, since the sum of those two fractions will give us the total amount of space occupied in the container.

First, let's find the fraction that represents the water. The container is 1/3 full of water, so the fraction representing the water is 1/3.

Next, let's find the fraction that represents the oil. The container is 1/4 full of oil, so the fraction representing the oil is 1/4.

To find the fraction of the container that is empty, we subtract the fraction representing the water (1/3) and the fraction representing the oil (1/4) from 1:

1 - 1/3 - 1/4

To subtract fractions, we need a common denominator. The least common multiple of 3 and 4 is 12, so we can rewrite the fractions with a denominator of 12:

12/12 - 4/12 - 3/12

Now, we can subtract the numerators:

(12 - 4 - 3)/12

Which simplifies to:

5/12

Therefore, the fraction of the container that is empty is 5/12.
