I think the answer to the input gear has 22 teeth on it and the output gear has 45 teeth on it is thst its reduction ratio is 3.3:1.

Solution:

Number of teeth on input gear= 22 teeth

Number of teeth on output gear= 45 teeth

Reduction=Number of teeth on output gear - Number of teeth on input gear

                 = 45 - 22

                  = 23

Reduction Ratio=(Number of teeth on output gear) / (Reduction)

[tex]=\frac{45}{23}\\\\ \frac{2}{1}[/tex]

→→Option C. 2: 1 is true.
