To solve this problem, first find the lowest common multiple of 12 and 15.

When solving systems of equations, students often struggle to identify the smallest common multiples of the coefficients before eliminating variables.

To add the fractions easily, we computed the lowest common multiples of the denominators.

The astronomers discovered a multiple star system hidden by dust in the nebula.

During the review session, the professor emphasized strategies for answering multiple-choice questions quickly and accurately.

Each multiple-choice question on the exam had one correct answer and three distractors.

The regional service used a refurbished diesel multiple unit to maintain frequent stops on the branch line.

On many regional lines, diesel multiple units provide reliable service where electrification is impractical.

Astronomers study multiple star systems to understand how planets form in complex gravitational environments.

Modern electric multiple units can accelerate faster than older diesel locomotives on commuter lines.
