-2 + (-1/3) equals what?

Answers

Answer:

-2 $(1)/(3)$

Step-by-step explanation:

Final answer:

To evaluate -2 + (-1/3), subtract -1/3 from -2, which simplifies to -7/3.

Explanation:

To evaluate -2 + (-1/3), we need to add the two numbers together. When adding negative numbers, we can think of it as subtracting the numbers.

So, -2 + (-1/3) is the same as -2 - 1/3. To subtract fractions, we need to have a common denominator.
The common denominator of 2 and 3 is 6, so -2 - 1/3 is equal to -12/6 - 2/6.
Subtracting -12/6 - 2/6 gives us -14/6. But we can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2. So, -14/6 simplifies to -7/3.
