Step-by-step explanation:
a) The significant figures in the number 99 is 2
The significant figures in the number 100 is 3
b) Uncertainty in each of the numbers for both the numbers is 1

Percentage uncertainty = 1.01
100

Percentage uncertainty = 1
c) Percentage uncertainty is a better way to express the numbers as the significant figures do not show the actual value of the numbers.
