Operations with LCD

Worksheet Description

This worksheet is centered on the mathematical concept of the least common denominator (LCD) and is designed to assist students in adding and subtracting non-like fractions, i.e., fractions with different denominators. It is labeled as “Worksheet 12” indicating it may be part of a larger set of worksheets. The problems presented are a mixture of simple fractions (not mixed numbers), and they require the student to either add or subtract them. The instructions are clear, asking the students to either add or subtract the following fractions with different denominators, suggesting that the exercises will require finding the LCD for each pair of fractions.

The worksheet aims to teach students the critical foundational math skill of finding the least common denominator when dealing with fractions that have different denominators. By working through these problems, students will learn how to identify the smallest common multiple of two or more numbers, which in this case are the denominators of the fractions. This skill is not only necessary for the addition and subtraction of fractions but is also a stepping stone to understanding more complex algebraic concepts involving fractions. Furthermore, the worksheet encourages the development of problem-solving abilities and reinforces the importance of careful arithmetic calculations.
