Answer: the "negative" exponent just indicates that the base number is now the reciprocal or flipped. (If that's what you mean with stuff like evaluating fractions)
Step-by-step explanation:
With dividing fractions, you might have to flip the fraction to divide it (for example, 1/2 divided by 3/8. You keep 1/2, change the division to multiplication, then flip 3/8 to 8/3 to get 7/8, which also requires finding a common denominator but that's easy. All you have to do is mulitply the one and two in 1/2 by 4 to get 4/8)
