The correct Answer is:
To solve the problem \(2 \frac{1}{2} + 2 \frac{1}{2} + 2 \frac{1}{2} + 2 \frac{1}{2} = ?\), we can follow these steps: ### Step 1: Convert the mixed number to an improper fraction The mixed number \(2 \frac{1}{2}\) can be converted to an improper fraction. \[ 2 \frac{1}{2} = 2 + \frac{1}{2} = \frac{2 \times 2 + 1}{2} = \frac{4 + 1}{2} = \frac{5}{2} \] ### Step 2: Write the equation with improper fractions Now, we can rewrite the original equation using the improper fraction: \[ \frac{5}{2} + \frac{5}{2} + \frac{5}{2} + \frac{5}{2} \] ### Step 3: Add the fractions Since all the fractions are the same, we can multiply the improper fraction by the number of times it appears (which is 4): \[ 4 \times \frac{5}{2} = \frac{4 \times 5}{2} = \frac{20}{2} \] ### Step 4: Simplify the fraction Now, simplify \(\frac{20}{2}\): \[ \frac{20}{2} = 10 \] ### Final Answer Thus, the answer is: \[ ? = 10 \] ---
