Find 3 rational numbers between 𝟏/πŸ’ and 𝟏/πŸ“ Since numbers don’t have the same denominator We take denominator as LCM of 𝟏/πŸ’ and 𝟏/πŸ“ i.e. 20 So, numbers are 1/4 = 1/4 Γ— 5/5 & 1/5 = 1/5 Γ— 4/4 So, now we need to find 3 rational numbers between 4/20 and 5/20 Since have to find 3 rational numbers, we multiply the numbers by 4/4 4/20 = 4/20 Γ— 4/4 & 5/20 = 5/20 Γ— 4/4 Thus, 3 Rational numbers between 1/4 & 1/5 are 17/80 , 18/80 , 19/80
