Equivalent/Equal ratios<em> - Definition of Equivalent Ratio A ratio can be represented as a fraction. The concept of an equivalent ratio is similar to the concept of equivalent fractions.

Answer:
Mean = -1,115,000 per year.
Step-by-step explanation:
Mean = (Σx)/N
The mean is the sum of variables divided by the number of variables
Σx = sum of variable = change in number of visitors over a 10 year period = -11150000
N = number of variables = 10
Mean = (-11150000)/10
Mean = -1,115,000 per year.
Hope this Helps!!!
