Consider the number line below. Using what you know about fractions and whole numbers on number lines, what fractions could be used to represent the whole numbers on this number line? Explain your reasoning.

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

b

step-by-step explanation:
