Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Add the numerators of the fractions.
  • Step 2: Keep the common denominator for the result.
  • Step 3: Simplify if necessary and confirm with answer choices.

Let's work through the solution step-by-step:

Step 1: Add the numerators.

The expression is 18+68 -\frac{1}{8} + -\frac{6}{8} .

The numerators are 1-1 and 6-6. Adding these gives:

1+(6)=16=7-1 + (-6) = -1 - 6 = -7.

Step 2: Write the result over the common denominator.

Since the denominator is 88, the fraction becomes 78 -\frac{7}{8} .

Step 3: Verify and finalize the result.

The result 78-\frac{7}{8} matches one of the multiple-choice options.

Therefore, the solution to the problem is 78 -\frac{7}{8} .

Answer

78 -\frac{7}{8}
