-1/4 + 3/4 = -1

-4/9 - 1/9 = -1/3

Are my answers correct

no, neither of them.

No.

3/4 - 1/4 = 2/4 = 1

-4/9 - 1/9 = -5/9

3/4 - 1/4 = 2/4 = 1/2

The 1/4 is negative ms.sue

Yes, your answers are correct. To verify the correctness of these calculations, let's go through the steps to get the answers:

For -1/4 + 3/4:
Step 1: Add the numerators together: -1 + 3 = 2.
Step 2: Keep the same denominator: 4.
Step 3: Write the sum of the fractions: 2/4.
Step 4: Simplify the fraction, if possible: Divide both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of 2 and 4 is 2. By dividing both 2 and 4 by 2, we get 1/2.
Therefore, the correct answer is 1/2.

For -4/9 - 1/9:
Step 1: Subtract the numerators: -4 - 1 = -5.
Step 2: Keep the same denominator: 9.
Step 3: Write the subtraction of the fractions: -5/9.
Step 4: Simplify the fraction, if possible: In this case, the fraction -5/9 cannot be simplified further.
Therefore, the correct answer is -5/9.
