In this problem we are trying to solve the diameter of the larger gear. I don't really understand the problem and I need help now!
Let,
Diameter of the larger gear х
So the equation for the problem is,
1/4х + 2.5 = 16
1/4х = 16 - 2.5
1/4x = 13.5
x = 13.5*4
x = 54
Hence, the diameter of the larger gear is 54 cm
