A carpenter is preparing materials for a custom shelving unit. Which of the following tasks requires the carpenter to find a Least Common Denominator (LCD) before performing the calculation?

A technician is joining two different lengths of scrap wire, one measuring 5/8 of a foot and the other measuring 1/3 of a foot. To calculate the total length of the combined wires, the technician must first find the ____.

In professional environments, fraction calculations are common. Match each workplace task with the correct rule regarding the requirement for a Least Common Denominator (LCD).

Identifying Fraction Operations Not Requiring an LCD

When a shipping clerk divides a fractional bulk weight by another fraction to determine the number of smaller packages that can be filled, a Least Common Denominator (LCD) must be identified as part of the calculation process.

In a professional inventory report, a manager must perform various fraction calculations. Arrange the following steps in the correct logical order to determine and apply the Least Common Denominator (LCD) requirement based on standard fraction rules.
