Yeah! If we see it as the 'difference' in the number of frogs which jumped to 3 1/2 feet and 6 1/4 feet it makes sense. Yesterday I went with another point of view like the 'quantity/number' of frogs which jumped to 3 1/2 and 6 1/4 feet, where I thought the first question is asking us how many less number of frogs jumped to 6 1/4 feet high compared to 3 1/2 feet height.
