Lecture 12 - Liner equations and graph of liner equations. After studying this chapter you will be able to understand: To understand the linear equations. to plot linear equations on the cartesian coordinate system. | General Mathematics ADE 101 LECTURE No. 3 Fractions and Operations on Fractions Today’s Objectives Students and Teachers will be able to Understand Fractions Learn about Types of Fractions Apply Operations on Fractions KNOWLEDGE TEST FRACTIONS Abdullah uses fractions to split up his pizzas How many parts will he cut it into if he is sharing with his brother Ayan? Abdullah splits the pizza into two equal parts. Each part is a fraction. We call these parts halves. It is important that they are equal. FRACTION IS TO BE CONSIDERED AS PARTS OF THINGS Which of these shapes are split into halves? One half can be written like this As you can see fractions are made up of 2 different parts. One part on the top and One part on the bottom A line between them The top number is the number of parts we have The bottom number is the total number of parts The top and bottom parts of the fraction have different meanings. Another name for these parts is The numerator The denominator The numerator is the top part. It shows how many parts of the whole we are talking about. The denominator is the bottom part. It shows how many parts the whole has been split into. 1/4 3 4 1/4 1/4 1/4 3 4 1/4 1/4 Which number is circled? 3 4 = numerator Which number is circled? 3 4 = denominator What fraction of the rectangle is blue? 4 6 What fraction of the rectangle is blue? 2 6 What fraction of the pie is blue? 4 4 What fraction of the pie is blue? 3 4 What fraction of the musical instruments have strings? 2 5 What fraction of the fish have stripes? 3 5 What fraction of the pins are knocked down? 3 10 You have math's tests out of 10 questions 6 are correct. ? ? ? ? ? ? ? ? ? ? You are getting 6/10. Activity Results Types of Fractions 0 1/2 1 2 Zero Fraction: when top number is zero and bottom number is any number. Proper Fraction: If top number is smaller than the bottom number the fraction is called proper fraction. This fraction is greater than zero but smaller than one.
