If by using the expression a fraction it is referring to the result being less than 1 then this only applies in certain cases.
1) If the number is greater than 1 on which the exponent is operating then the resultant will have a value less than 1.
Example : 2-3 = 1/23 = 1/8 = 0.125 : 3-1/3 = 1/31/3 = 0.693
2) If the number is less than 1 on which the exponent is operating then the resultant value will be greater than 1.
Example : 0.5 -2 = 1/0.52 = 1/0.25 = 4
Basically do the same thing you would with a positive exponent. However, the difference with negatives is that it will be a fraction with 1 over whatever the exponent comes out to. The negative just tells you to flip the position of the exponent from the numerator to the denominator. For example if you have 5-2, it would become 1/52, which would then become 1/25. Also, if you have a negative exponent in your denominator, you would flip it up to the numerator. For example if you have 1/5-2, it would become 52, which would then be 25.
scientific notation tells how many times you will move or add zero either left(positive) or right (negative). exponent tells you how many times you will multiply its coefficient.
