MATHEMATICS FORM 1 – FRACTIONS msomimaktaba, November 11, 2018August 17, 2024 FRACTIONSA fraction is a number that can be written in the form of Where a and b are intergers and b 0 The number which is written on top of fraction is called Numerator and the bottom is called denominator e.g Type of fraction(i) Proper fractions– A proper fraction is the one in which the numerator is less than denominator e.g. etc(ii) Improper fractions– These are the ones which the numerators are greater than the denominatoretc(iii) Mixed fractions or mixed numbers– These are the ones formed after improper fractions are divided complete e.g. = 2, 6, 9(iv) Equivalent fractionsThese are two or more fractions that can be simplified to equal lowest fraction.Example: Change the following into mixed numbers 1. = 7 2. = 3 3. = 6 Fractions can be represented on number linese.g. represent on a number line.Exercise 1 1. (i)Which of the following are: –(a) Proper fractions (b) Mixed fractions(c) Improper fractions(ii) List four equivalent fractions(i) (ii) (iii) (iv) (v) (vi) (vii) (viii) (ix) (x) (xi) (xii) (xiii) (xiv) (xv) (xvi) 3 Solution(a) Proper fraction, , , , , , , , , (b) Improper fraction, , , , (c) Mixed fraction1, 3Four equivalent fractions are:- 1. , 2. , 3. , 4. , 2. Write the following fractions in words (a) three quarters (b) A half(c) A third (d) Five over six(e) Nine over Ten(f) A quarter 2. Write the name of the fraction of the shaded part in figures ABCD and EFGH = one over three (A third)Which is a proper fraction EH F G= one over four (A quarter)Which is a proper fraction Comparison of fractionFraction can be compared by using two methods(i) Number line(ii)L.C.M of the denominators (I) Number line Example 1. show and on a number line and then find which is greater than the other Example 2. Which is greater between and ?Solution: (II) L.C.M of the denominatorsDetermine which fraction is greater between and Solution1st find the L.C.M of 5 and 7L. C. M of 5 and 7 = 352nd multiply by that L. C. M each fraction35 = 1435 = 20Conclusion, check the one which has given us bigger number after multiplication with L.C.M Example: which is greater or ?Solution:L.C.M = 4444=9944=12:- Operations on FractionsAddition and Subtraction of FractionNOTE: 1 .Add the numerator together if each fraction has the same denominator.2. If the fraction has different denominator, you must find the smallest number that each denominator divides into exactly. (LCM)3. When adding fractions, do not add the denominator.Example:Evaluate the following fractionsMultiplicationNOTE: 1. Before multiplying a number convert mixed number into improper fractions 2. Multiply the numerators and multiply the denominator. Examples:Dividing Fractions1. When dividing fractions invert the second fraction then multiply the first fraction by the inverted fraction. 2. Before dividing number convert mixed numbers into improper fraction.
