Answer:
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs)
Subtract 4 from both sides
R/10 = 5 - 4
Simplify 5 - 4 to 1
R/10 = 1
Multiply both sides by 10
R = 1 × 10
Simplify 1 × 10 to 10
<u>R = 10</u>
