There are 1/3 pieces of pie left over on each
plate. How much pie is left over in total?

An entity can be divided in fractions or ratios. The total number of pie left over on N plates is

Given that:

--- the fraction left over

The total number of pie left over is

Where N is the number of plates

So:

For instance

If N is 6, the number of pie will be 2: i.e.

If N is 12, the number of pie will be 4: i.e.

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.
