Mathematics Topic: Fractions General Instructions: 1) Do not copy the questions. 2) Solve the assignment in your Mathematics notebook. 3) Write proper steps and reasons wherever necessary. Let us first recapitulate those points which have been already discussed in the previous assignment. Meaning of fraction and its various types Types of fractions Proper Improper Mixed Like Unlike Equivalent Lowest or simplest form of fraction To simplify a fraction, divide the numerator and denominator by the highest number that can divide both the numbers exactly. Comparison of fractions 6 P a g e
Addition and subtraction of fractions Now further, we will study about multiplication and division of fractions. Multiplication of fractions There are three simple steps to follow while multiplying fractions: 1. Multiply the numerators (top numbers) 2. Multiply the denominators (bottom numbers) 3. If needed, simplify or reduce the fraction to its lowest form. Thus to multiply fractions we follow the rule given below: RULE Product of two or more fractions = Product of their numerators Product of their denominators Example 1: 2 5 5 18 2 5 = = 5 18 10 90 10 10 = = 90 10 1 9 We can also represent the above product like this: 1 2 2 X 5 18 5 1 = 1 X1 = 1 1 5 X 5 = 18 X 9 9 1 9 Example 2: 2 2 2 14 5 = = = 1 9 1 9 1 9 9 = 9 Re-writing whole numbers by taking the denominator as ONE P a g e
Example 3: 1 2 1 33 2 8 2 = 4 5 11 4 5 = = 69 = 10 23 11 33 3 4 2 1 23 X X 5 11 2 1 3 X1 X23 2 X 5 X 1 Convert mixed fractions into improper fraction and then follow the same steps to find the product. 9 = 6 10 Note In the same way, we will deal with the concept fraction of a whole number and fraction of a fraction. What is of? 8 P a g e
Multiplicative Inverse It is also known as the reciprocal of a number. It is obtained by interchanging the numerator and denominator. Multiplying a number by its reciprocal always give you one. Division of fractions Rule: To divide by a fraction, multiply by its reciprocal. Example 1: 2 14 14 = 14 = 2 1 2 = 14 X 1 2 = 1 X 1 X 1 = 49 1 = 49 Example 2: 4 22 11 22 2 11 = = 9 9 1 9 1 11 = 2 22 9 X 11 1 = 1 2 X 1 9 X 1 = 2 9 9 P a g e
