Rank the three fractions from smallest to largest? and why
2/7, 4/14, 8/11

2/7 = 4/14 so from smallest to largest the fractions are:

2/7 4/14 and 8/11

Step-by-step explanation:

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.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
