When fraction have common denominator, you just add the numerator and write the sum over the common denominator and write the lowest term. This time, learn more about addition and subtraction of fraction. In this lesson, you are expected to add and subtract fractions and mixed frac tion with and without regrouping There is an activity below which will give you a review of this new lesson. Learning Task 1: Add or subtract the following fractions. Write you answer on your notebook. a) 3 = 18 18 bj 3 8 86 19 d) 9- 32 = 6 104 - 55 10 10 D Let us look at the problem situation below. Ruel jogged 5 of a kilometer on Saturday and of a kilometer on Sunday. How far did jog together in 2 days? Solution: The fraction 3 and 4 are dissimilar. To find the total distance he jogged, we add 3 and Rename the fraction Find the LCD. Add.

PIVOT 4A CALABARZON 20Solves Routine and Non-routine Problems Involving Addition or Subtraction of Fractions I Lesson After going through this lesson, you are expected to solve routine and non routine problems involving addition and subtraction of frac- tions using appropriate problem solving strategies and tools. Learning Task 1. Find the sum or difference, Express each answer in lowest term. Write your answer in your notebook. 10 5 8 12 40 10 24 12 28 28 56 28 5 9 2 15 4 10 12 18 + 10 16 12 28 28 18 18 27 36 D Study the problem. Look for the solution. Marlon has Php 720. 00. He spent 2/3 of it on a ballpen and Php 90.00 on a drink. How much money did he have left? Php. 720.00 2/3 of Php 720.00= Php 480.00 for ballpen 2/3 1.) Add first, Php 480.00 (ballpen) and Php 90.00 Solution: Php 480.00 - ballpen 2.) Subtract Php 570.00 from Php + 90.00 - drink 720.00 Php 570.00 Php 720.00 - 570.00 Php. 130.00 PIVOT 4A CALABARZON 22Example: Find the difference of 9 - and 3 5.

Write you answer on your notebook. + 9 3) 84 5) 24 3 = 3 18 6 12 8 2) 10 - 6 4) 94 - 71 5 15 61 120 +53- 10 10 A To add and subtraction similar fraction, simply add or subtract the numerator and copy the denominator. To add or subtract fractions with dissimilar denominators, get the LCD. Change the fractions to similar fractions or equivalent fractions using the LCD. Then, add or subtract the equivalent fractions. To subtract mixed forms with dissimilar fractions, make the fraction similar. If the fraction in the minuend is less than the fraction in the subtrahend, rename the minuend as a mixed form with a fraction greater than one. Learning Task 3: Subtract the following fractions. Write you an- swer on your notebook. 1) 4 5 3) 80 41 5) 4 = 10 15 10 12 12 4) 7 3 64 6) 2) 11 - 62 = 15 0 - 113 8 25 15 25 10 PIVOT 4A CALABARZON 21 MATHS
