Agear ratio is the ratio of the teeth on the front sprocket and the teeth on the rear sprocket. if a bike has 36 teeth on the front sprocket and 12 rear teeth, what is the gear ratio for the bike

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

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
