Answer:
The gear ratio of the bike = 3:1
Step-by-step explanation:
Question:
A gear 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 teeth on the rear sprocket, what is the gear ratio for the bike?
Given:
Number of teeth on the front sprocket = 36
Number of teeth on the rear sprocket = 12
To find the gear ratio for the bike.
Solution:
The gear ratio of a bike is the ratio of the number of teeth on the front sprocket and the number of teeth on the rear sprocket.
Thus, the gear ratio can be given as:
⇒
Reducing to simple fraction by dividing the numerator and denominator by their GCF.
⇒
⇒
Thus the gear ratio can be given = 3:1
There is nothing to do with it. If it gives you x=# or y=# then you can plug it in, but otherwise, this is the simplest way to write this equation.
If you want to go further, you can figure out that
y= 7-x
but that's about it.
In division problems, if the division results in a decimal or fraction, (not a whole number), than it has a remainder. If the division results in a whole number, then there is no remainder, or a remainder of zero.
Examples:
6/3=2
6/4=1.5
0.06p = 0.72
p = 12
The original price was $12.
$20.70= 3p +3
This is the equation yo represent the situation
