Respuesta :
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.
