Iwill make you the brainliest easy question write the dimensions of the room as mixed numbers. remember 1 foot = 12 inches. what does the fractional part of each mixed number represent? the numbers are 13 feet 8 inches and 12 feet 3 inches

Part of a foot.

13 2/3 of a foot.

12 1/4 of a foot.

Step-by-step explanation:

The fractional part of each measurement means the portion of a foot. Since a foot is 12 inches, its the number of inches out of 12.

13 feet 8 inches is 13 8/12 which simplifies to 13 2/3 of a foot.

12 feet 3 inches is 12 3/12 which simplifies to 12 1/4 of a foot.

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.
