Correct option is B
2⅗ + 3½ − ⅗ = (2 + 3) + (3/5 + 1/2 − 3/5) = 5 + 1/2 = 5½
Explanation of options: (a) ✘ 7½ is an overestimation due to miscalculation in fractions. (b) ✔ Correct simplification gives 5½. (c) ✘ 6½ includes extra 1 from over-added fractional parts. (d) ✘ 8½ is clearly incorrect based on total value.
