2. Math Class Prayer Dear Lord, Thank you for the hundredfold blessings in our life. Help us to multiply love with one another. Divide our God given talent. May we add happiness and positive thoughts to everybody. And subtract wrongdoings and grudges in our hearts. This we ask in Jesus name…. Amen

3. Introduction to Rational Algebraic Expression .

4. Hello class…. Tell me with emoji you’re feeling today… Which emoji are you today??

5. Let’s have a Drill… Translate the following statements into symbols using the assigned code for each tropical fruit found in the Philippines. Every number has a hidden letter to decode the word. Let p = pineapple b = banana a = avocado c = coconut

6. The quotient of pineapple and banana. The sum of avocado and coconut divided by their difference. The reciprocal of the product of pineapple and banana. The square of pineapple added to twice the pineapple One-third of the square of “avocado”. Three times the square of the coconut divided by twice of pineapple. The product of avocado and pineapple diminished by twice of banana. Half of the product of avocado, banana, coconut and pineapple

7. Motive Question 1. What is a rational algebraic expression? 2. How do you know if the algebraic expression is rational or not?

8. Illustrative Example: These are clouds and inside the clouds are algebraic expressions. Can you distinguish from the clouds which are rational algebraic expressions, and which are not? Those that belong to Rational Algebraic Expressions will state the weather forecast for today and those that belong to Not Rational Algebraic Expressions is the things to bring during these days’ weather forecast.

12. CLASSIFY ME Classify the different expressions into rational algebraic expression or not rational algebraic expression, use the clue given in each box. Write the expressions into the appropriate column. Hi, I’m Jimin Park of BTS from South Korea and I will visit 2 of the most famous cities in the Philippines. And these are my itineraries. Can you guess what are the 2 cities that I will visit?

14. What is a Rational Algebraic Expression? Generalization A rational algebraic expression is one that can be expressed as quotient / ratio of 2 polynomials with a denominator not equal to 0. It is in the form , where b  0.   If the algebraic expression involves variable raised to fractional exponents and independent variables appear under a radical sign, then it is not a rational algebraic expression. How do you know if the algebraic expression is rational or not?
