So, we need to figure out how much times the body size of the flea it can jump. First, we need to figure out the size of the flea: 2^-4=0.0625
Now that we have the size of the flea, we need to figure out how high it can jump: 2^3=8
After we figure out the size of the flea, we need to divide 8 by .0625 because it is inverse operations to multiplication: 8/.0625=128
Answer: The flea can jump 128 times higher than it's body size.
