The three dots after a number which indicate that the decimals continue without end. Is a number that represents a part of a whole. It consists of a numerator and denominator. Is a number that represents a part of a whole. It is written to the right of the unit’s place separated by a period. It is the horizontal number line above a number which indicates that the number/s is/are in infinite repeating pattern. ACTIVITY: LOOP- A- WORD

6. ACTIVITY 1 : A. Match the fraction in Column A to its corresponding decimal form in Column B. A B ______ 1. ¹⁄ ₂ a. 0.4 _____ 2. ¹⁄₄ b. 0.333… _____ 3. ¹⁄₃ c. 0.5 _____ 4. ⁴⁄₁₀ d. 0.25 B. Change the following decimal form to fraction form. 1. 0.9 2. 0.25 3. 0.3

7. ANSWER: A. 1. ¹⁄ ₂ = c. 0.5 B. 1. 0.9 = ⁹⁄₁₀ 2. ¹⁄ ₄ = d. 0.25 2. 0.25 = ² ⁵⁄₁₀₀ = ¹⁄₄ 3. ¹⁄ ₃ = b. 0.333… 3. 0.3 = ¹⁄ ₃ 4. ⁴⁄₁₀ = a. 0.4

8. I will divide you into two groups. Name your group and select a leader. Each group will be given an activity envelope where you will find the materials for the activity and the exercises that your group will be going to solve. ACTIVITY 2

9. Each group will be given an activity envelope where you will find the materials for the activity and the 3-item test that your group will be going to solve. The leader will be the responsible for dividing the tasks between the members of the group . The group activity will be scored according to this standard. EVALUATION:

12. EXTEND: Answer the following problems: San Roque National High School was established in the year 1995. It is located at Barangay Del Rosario, Mercedes Camarines Norte. In a survey, three out of ten students said they prefer to eat at school canteen rather than going at home for their lunch. Express ³⁄ ₁₀ in decimal form. In Mercedes, the main source of income is fishing. If Dante bought 10.75 meters long of fishing net, how could he express it in fraction?

13. ANSWER: 0.3 10.75 = 10 ⁷⁵⁄₁₀₀ = 10 ³⁄₄ or ⁴³⁄₄
