Question 1 (l) Add the following fractions using Brahmaguptaβs method: (l) 2/3+4/5+3/7 To find common denominator of these fractions We need to find LCM Common denominator = LCM of 3, 5, 7 = 3 Γ 5 Γ 7 = 105 Now, making denominator 105 of all these fractions π/π=2/3 Γ35/35 =ππ/πππ π/π=4/5 Γ21/21 =ππ/πππ π/π=3/7 Γ15/15 =ππ/πππ Our sum becomes 2/3+4/5+3/7 = 70/105+84/105+45/105 = (70 + 84 + 45)/105 = πππ/πππ
