This learning unit clearly explains how to read fractions of an inch, with a strong focus on eighth-inch measurements (such as 1/8, 3/8, 5/8, and 7/8). Starting with a quick review of half-inch and quarter-inch increments, learners move step-by-step toward accurately identifying and using eighth-inch markings on rulers and tape measures. The unit includes a short video lesson, practice exercises, and certification quizzes to help learners build confidence and verify their skills.
