Answer 1

Answer:

Ratio will be : $\frac{3}{1}$

Step-by-step explanation:

A gear ratio is the ratio of the teeth on the front sprocket and the teeth on the rear sprocket.

When a bike has 36 teeth on the front sprocket and 12 rear teeth, the gear ratio will be :

$\frac{36}{12}=\frac{3}{1}$

We can also write this as 3:1

Answer 2

Answer:

3 : 1

Step-by-step explanation:

ratio = teeth on front sprocket : teeth on rear sprocket

       = 36 : 12 ( divide both parts of the ratio by 12 )

       = 3 : 1 ← in simplest form
