The correct Answer is:
To solve the problem, we need to perform the following steps: 1. **Calculate the sum S1**: This is the sum of \(-\frac{4}{7}\) and \(\frac{5}{14}\). 2. **Calculate the sum S2**: This is the sum of \(\frac{9}{14}\) and \(\frac{23}{14}\). 3. **Subtract S1 from S2**: This will give us the final result. Now, let's go through each step in detail: ### Step 1: Calculate S1 We need to find the sum of \(-\frac{4}{7}\) and \(\frac{5}{14}\). To add these fractions, we need a common denominator. The least common multiple of 7 and 14 is 14. Convert \(-\frac{4}{7}\) to a fraction with a denominator of 14: \[ -\frac{4}{7} = -\frac{4 \times 2}{7 \times 2} = -\frac{8}{14} \] Now we can add: \[ S1 = -\frac{8}{14} + \frac{5}{14} = \frac{-8 + 5}{14} = \frac{-3}{14} \] ### Step 2: Calculate S2 Next, we find the sum of \(\frac{9}{14}\) and \(\frac{23}{14}\). Since both fractions have the same denominator, we can add them directly: \[ S2 = \frac{9}{14} + \frac{23}{14} = \frac{9 + 23}{14} = \frac{32}{14} \] ### Step 3: Subtract S1 from S2 Now, we need to subtract S1 from S2: \[ S2 - S1 = \frac{32}{14} - \left(-\frac{3}{14}\right) = \frac{32}{14} + \frac{3}{14} = \frac{32 + 3}{14} = \frac{35}{14} \] ### Simplifying the Result Now, we can simplify \(\frac{35}{14}\): \[ \frac{35}{14} = \frac{35 \div 7}{14 \div 7} = \frac{5}{2} \] ### Final Result Thus, the final result is: \[ \frac{5}{2} \text{ or } 2.5 \]
