This module was designed and written with you in mind. It is here to help you master subtraction of fractions and mixed numbers. The scope of this module permits it to be used in many different learning situations. The language used recognizes the diverse vocabulary level of students. The lessons are arranged to follow the standard sequence of the course. But the order in which you read them can be changed to correspond with the textbook you are now using.

The module is divided into three lessons, namely:

• Lesson 1. Subtracting Simple Fractions Without Regrouping

• Lesson 2. Subtracting Simple Fractions from Mixed Numbers Without Regrouping

• Lesson 3. Subtracting Simple Fractions from Mixed Numbers With Regrouping

After going through this module, you are expected to:

1. subtract simple fractions without regrouping; **(M6NS-Ia-86)**

2. subtract simple fractions from mixed numbers without regrouping; **(M6NS-Ia-86)**

3. subtract simple fractions from mixed numbers with regrouping; **(M6NS-Ia-86)** and

4. solve routine and non-routine problems involving addition and/or subtraction of fractions using appropriate problem-solving strategies and tools. **(M6NS-Ia-87.3)**
