Question

GEAR RATIOS

AUTOMOBILE TRADES: In an automobile engine, the driven gear has 128 teeth and the
ratio?
driver gear has 16 teeth. What is the gear r

Answer 1

8:1

Explanation:

The gear ratio is determined by dividing the number of teeth on the driven gear by the number of teeth on the driver gear.

In this case:

`\sf \textsf{Gear Ratio} = \frac{\textsf{Number of Teeth on Driven Gear}}{\textsf{Number of Teeth on Driver Gear}}`

Substitute the given values:

`\sf \textsf{Gear Ratio} = (128)/(16)`

Simplify the fraction:

`\sf \textsf{Gear Ratio} = 8`

Therefore, the gear ratio in this automobile engine is
`\sf 8:1`.
