Determine the gear ratio for a bike with 45 front teeth and 18 rear sprocket teeth.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
