The correct Answer is:
To find out what should be added to \(-\frac{6}{8}\) to get \(\frac{5}{6}\), we can follow these steps: ### Step 1: Set up the equation Let \(x\) be the number that we need to add to \(-\frac{6}{8}\). The equation can be set up as: \[ -\frac{6}{8} + x = \frac{5}{6} \] ### Step 2: Isolate \(x\) To find \(x\), we can rearrange the equation: \[ x = \frac{5}{6} + \frac{6}{8} \] ### Step 3: Find a common denominator The denominators of the fractions are 6 and 8. The least common multiple (LCM) of 6 and 8 is 24. We will convert both fractions to have this common denominator. ### Step 4: Convert \(\frac{5}{6}\) to have a denominator of 24 To convert \(\frac{5}{6}\): \[ \frac{5}{6} = \frac{5 \times 4}{6 \times 4} = \frac{20}{24} \] ### Step 5: Convert \(\frac{6}{8}\) to have a denominator of 24 To convert \(\frac{6}{8}\): \[ \frac{6}{8} = \frac{6 \times 3}{8 \times 3} = \frac{18}{24} \] ### Step 6: Add the two fractions Now we can add the two fractions: \[ x = \frac{20}{24} + \frac{18}{24} = \frac{20 + 18}{24} = \frac{38}{24} \] ### Step 7: Simplify the fraction Now we simplify \(\frac{38}{24}\): \[ \frac{38}{24} = \frac{19}{12} \] ### Final Answer Thus, the number that should be added to \(-\frac{6}{8}\) to get \(\frac{5}{6}\) is: \[ \frac{19}{12} \] ---
