The grasshopper, the frog and the mouse had a jumping contest. The grasshopper jumped 21 inches. The grasshopper jumped 25 inches farther than the frog and the mouse jumped 16 inches lesser than the frog. How much farther did the grasshopper jump than the mouse?
First, we need to find how much the frog jumped. The frog jumped 21 inches, the grasshopper jumped 25 inches farther than the frog, and the mouse jumped 16 inches lesser than the frog, so we can say that the frog jumped 21 + 25 - 16 inches, which is the same as 21 + 9 inches, or 30 inches. 

Next, we need to find how much the mouse jumped. The mouse jumped 16 inches lesser than the frog, so we can say that the mouse jumped 30 - 16 inches, which is the same as 14 inches. 

Now, we need to find the difference between how much the grasshopper jumped and how much the mouse jumped. The grasshopper jumped 21 inches and the mouse jumped 14 inches, so the difference is 21 - 14 inches, which is the same as 7 inches. 

Therefore the answer (numeric) is: 

7
