Answer:

The wing of the dragonfly was 9.65 cm longer than that of the fly, 102% larger in percentage terms.

Step-by-step explanation:

Since the length of the wing of the old dragonfly was 19.5 cm, while the length of the wing of a common fly is 9.85 cm, to determine how long the dragonfly's wing was compared to that of the fly, the following must be done calculations:

19.5 - 9.85 = X

9.65 = X

Thus, the wing of the dragonfly was 9.65 cm longer than that of the fly. In turn, in terms of percentages, the result is the following:

9.65 = 100

19.5 = X

19.5 x 100 / 9.65 = X

1950 / 9.65 = X

202 = X

Thus, in percentage terms, the dragonfly's wing was 102% larger than that of the current fly.
