Ex 7.4 ,2 Compare the fractions and put an appropriate sign. (a) 3/6 "β" 5/6 3/6 "β" 5/6 Since denominator is same, fraction with larger numerator is large. π/π < π/π Ex 7.4 ,2 Compare the fractions and put an appropriate sign. (b) 1/7 "β" 1/4 1/7 "β" 1/4 Here the denominators are different. So, we cross multiply 1 Γ 4 "β" 1 Γ 7 4 "β" 7 4 < 7 β΄ 1/7 < 1/4 1/7 "β" 1/4 Here the denominators are different. So, we cross multiply 1 Γ 4 "β" 1 Γ 7 4 "β" 7 4 < 7 β΄ 1/7 < 1/4 4/5 "β" 5/5 Since, the denominator is same, fraction with larger numerator is larger. π/π < π/π Ex 7.4 ,2 Compare the fractions and put an appropriate sign. (d) 3/5 "β" 3/7 3/5 "β" 3/7 Here, the denominators are different So, we cross multiply. 3/5 "β" 3/7 3 Γ 7 β 3 Γ 5 21 β 15 21 > 15 β΄ π/π > π/π
