-8/9 - (-2/9)?

1 answer

To solve this expression, we follow the rules of subtraction. When subtracting a negative number, we change the subtraction operation to addition and change the sign of the number being subtracted.

So, we have:

-8/9 - (-2/9)

Rewriting the expression, we change the subtraction to addition and the sign of the second term:

-8/9 + 2/9

Now, we can add the two fractions together:

-8/9 + 2/9 = (-8 + 2) / 9

Simplifying the numerator:

(-8 + 2) / 9 = -6/9

Finally, we reduce the fraction if possible:

-6/9 = -2/3

Therefore, -8/9 - (-2/9) equals -2/3.
