Explanation Given: A fraction 21 12 and a fraction 23 24 . Calculation: The given fractions have different numerators and different denominators. The fractions are of the form a b − c d and are unlike fractions. Where, ► a and c are the numerators ► b and d are the denominators For the subtraction of fractions, denominator of all the given fractions must be same. Find the LCD of the all the denominators given, to make the denominators same. First find the prime factors of the denominators. 12 = 2 ⋅ 2 ⋅ 3 24 = 2 ⋅ 2 ⋅ 2 ⋅ 3 Now multiply the different factors of each denominator, taking common factors one time. LCD = 2 ⋅ 2 ⋅ 2 ⋅ 3 = 24 The LCD of 12 and 24 is 24 . Here the LCD is same as the denominator of one fraction...
