\newline

Write your answer as a fraction or as a whole or mixed number.

\newline

______

Calculate Total Tape Needed: Determine the total amount of electrical tape needed and the amount of tape on each roll. $\newline$ The electrician needs $8,000$ centimeters of electrical tape, and each roll contains $2,000$ centimeters of tape.
Determine Rolls Needed: Calculate the number of rolls needed by dividing the total amount of tape needed by the amount of tape on each roll. $\newline$ Number of rolls needed $= \frac{\text{Total amount of tape needed}}{\text{Amount of tape in each roll}}$ $\newline$ Number of rolls needed $= \frac{8,000\,\text{cm}}{2,000\,\text{cm}}$
Perform Division: Perform the division to find the number of rolls. $\newline$ Number of rolls needed = $8,000 \div 2,000$ $\newline$ Number of rolls needed = $4$
