Mathematics iv ppt. PRESENTATION ON ADDING FRACTIONS
- 2. Adding similar fraction and dissimilar fraction.
- 4. Match the improper fraction in Column A to Its Corresponding Mixed Number in Column B. A B 12/5 5 1/10 7/2 5 1/3 18/4 2 2/5 32/6 4 ½ 51/10 3 1/2 Let us check!
- 5. Match the improper fraction in Column A to Its Corresponding Mixed Number in Column B. A B 12/5 5 1/10 7/2 5 1/3 18/4 2 2/5 32/6 4 ½ 51/10 3 1/2
- 7. Study the problem: Rj has 2/3 meter of a rope. Jonathan has another 1/3 meter of a rope. How many meter of rope do they have? To find out the total number of rope, add 2/3 and ½. 2/3 + 1/3 = 3/3 (3/3 is equal to 1. So, they have total meter of rope)
- 8. ¼ + 2/4 = ¾ 1/3 + 1/2 = (2/6 + 3/6) = 5/6 How???
- 9. Step 1: Add the numerators. 1 + 2 = 3 Step 2: Copy the same denominator. (4) Answer: 3/4
- 10. Step 1: Get the Least Common Multiple a. Get the new denominator. Multiply the denominators 3 and 2 ( 6) b. Get the new numerator. Divide the new denominator (6) by the former denominator (3 and 2) and multiply it to numerator (1 and 1). 6 ÷ 3 = 2 × 1= 2 use the same denominator 2/6 6 ÷ 2 = 3 × 1 = 3 use the same denominator 3/6
- 11. Step 2: Follow the same step in adding similar fraction. Add the numerators. Copy the same denominator. 2/6 + 3/6 = 5/6 Answer: 5/6
- 12. How do we Add Similar Fractions? How do we Add Dissimilar Fractions?
- 21. How do we Subtract Fraction then? That will be ur Assignment
