Answer:
The percentage difference between 3.4 and 3.42 is 0.58651% or 0.02.
Step-by-step explanation:
Find the absolute difference between two numbers: |20 - 30| = |-10| = 10
Find the average of those two numbers: (20 + 30) / 2 = 50 / 2 = 25
Divide the difference by the average: 10 / 25 = 0.4
Express it as percentages: 0.4 * 100 = 40%
in this case, it would be 3.4 and 3.42
