The document provides a set of exercises for adding and subtracting simple fractions and mixed numbers, including problems with or without regrouping. It includes example problems, guided practice, individual activities, application questions, and assessments, all aimed at helping students practice and express their answers in simplest form. Instructions cover finding the least common denominator (lcd) and performing calculations while emphasizing steps for arriving at the final answers.

1. MATHEMATICS
Adding and subtracting simple fractions and
mixed numbers without or with regrouping

2. Drill
1.) 3/4 and 2/3
2.) 1/3 and 1/2
3.) 1/8 and 5/6
4.) 1/6 and 3/5
5.) 1/8 and 3/4
Direction: Give the Least Common Denominator (LCD) of the
following pairs of dissimilar fractions. Write the answer on your
answer sheet.

3. REVIEW
1. 4/10
+ 1/5
2. 1/7
+ 1/4
3. 2/9
+ 6/9
Add the following fractions. Express your answer to simplest
form or lowest term, if needed. Write your answers on your
answer sheet.

4. Lets Try!
Look at the problem situation below.
Estelle has 3/4 meter of linen cloth.
She used 2/3 meter for one placemat.
What part of the linen cloth was left?
Solution: To find what part of linen
cloth was left, we subtract 2/3 from
3/4 .
Find: 3/4 – 2/3 = N
Therefore, 1/12 meter of the linen
cloth was left.
Here are some examples for you to
study.

7. ACTIVITY 2 (Fair and Share)
Direction: Add the following and change your answer to the lowest
term if needed. Write your answer on your answer sheet.

8. ACTIVITY 3 Individual activity
Add the following fractions. Write your answers on your
answer sheet.

2. 4/7 + 2/3
3. 5/9 + 2/3
4. 3/4 + 4/5
5. 1/2 + 3/5

9. REMEMBER
• In adding simple fractions without regrouping: 
Find the Least Common Denominator (LCD). 
Rename the dissimilar fractions to their equivalent
fractions using the LCD.  Add the numerators.
Then, write the sum over the common denominator.
 Express the answer in simplest form or lowest
term, if needed.
