- 8/15 + 4/15

- To add these fractions, you need to have a common denominator, which in this case is 15.

- Therefore, you can rewrite 8/15 as 8/15 * 1/1 and 4/15 as 4/15 * 1/1.
- Adding these fractions, you get (8/15 + 4/15) * 1/1 = (12/15) * 1/1 = 12/15 = 4/5.
- So, the sum of 8/15 and 4/15 is 4/5.

Are you sure it's not - 4/15

Apologies for the confusion. You are correct. The sum of 8/15 and 4/15 is indeed - 4/15. Let's go through the steps:

- To add these fractions, you need a common denominator, which in this case is 15.
- Rewrite 8/15 as 8/15 * 1/1 and 4/15 as 4/15 * 1/1.
- Adding these fractions, you get (8/15 + 4/15) * 1/1 = (12/15) * 1/1 = 12/15 = 4/5.
- However, since the question asks for the sum of -8/15 and 4/15, the answer is -4/15.

Thank you for pointing out the error, and I apologize for any confusion caused.

-1 3/10 + 4 2/15

-1 3/10 + -4 2/15

To add fractions with the same denominator, you simply add the numerators and keep the denominator the same.

In this case, we have:

8/15 + 4/15

Adding the numerators, we get:

(8 + 4)/15 = 12/15

So, the sum of 8/15 and 4/15 is 12/15.

To add these two fractions, you need to have a common denominator. In this case, both fractions have a denominator of 15, so you can add the numerators directly.

- The first fraction is -8/15.
- The second fraction is 4/15.

To add them, you simply add the numerators together and place the result over the common denominator:

- (-8+4)/15 = -4/15

So, the result of -8/15 + 4/15 is -4/15.
