In a ratio of measurements for the same kinds of units, units get canceled. For example, in a ratio of 3 meters / 8 meters, you can cancel the "meters" in the numerator and the denominator. An important ratio is pi, which is the ratio of the circumference of a circle to its diameter. If you measure the circumference in feet, and the diameter in feet, then divide circumference/diameter, then the result is the dimensionless quantity 3.14159265.... If you go back and measure both in meters, you get the same answer.
In a ratio of two measurements, the units cancel, so it makes no difference whether you write the units, or not.

No, it is a ratio - without units.
Why are coefficients of friction unitl-ess values?
Coefficients of friction are unitless values because they represent the ratio between the force necessary to overcome friction and the force pressing two surfaces together. Since the units cancel out in this ratio, coefficients of friction are expressed as pure numbers without units.

What are the units of efficiency?
Efficiency is typically expressed as a percentage, representing the ratio of useful output to input. It can also be expressed as a dimensionless ratio or a specific unit depending on the context, such as miles per gallon for fuel efficiency or lumens per watt for electrical efficiency.
