6. ARIEL C. RIGOR, LPT Addition and subtraction of fractions

7. OBJECTIVES AT THE END OF THE LESSON, THE STUDENTS WILL BE ABLE TO; Perform addition and subtraction of fraction; and Solve problems involving addition and subtraction of fractions.

8. Addition of FRACTION Add fraction only when they are like fractions. Like fractions have the same denominator. Add the numerators and place the sum over the common denominator. Simplify the result when necessary.

9. Addition of FRACTION But if fractions are unlike, determine first the least common denominator (LCD). The LCD is the least common multiple of the denominators of the fractions. Change each unlike fraction to an equivalent fraction with the LCD as a common denominator. Add the resulting fractions as before.

10. EXAMPLES   Direction : Find the sum of the following fractions       3   3  

11. Subtraction of FRACTION In a similar manner, subtract fractions only when they are like fractions. Subtract the numerators and place the difference over the common denominator. Simplify the result whenever necessary.

12. Subtraction of FRACTION To subtract unlike fractions , find the LCD. Change each unlike fraction to an equivalent fraction with the LCD as the common denominator. Subtract the resulting fractions as before.

13. EXAMPLES   Direction : Find the difference of the following fractions     4   6   10
