Question 7 Find 5 rational numbers between 1/6 and 2/5. First, we make the numbers have same denominator Now, Common denominator = LCM of 6 & 5 = 2 × 3 × 5 = 30 So, our numbers become 1/6 = 1/6 ×5/5 2/5 = 2/5 ×6/6 Now, we need to find 5 rational numbers, Since 𝟓/𝟑𝟎 & 𝟏𝟐/𝟑𝟎 have 5 rational numbers between them We can write it directly So, 5 rational numbers between 1/6 and 2/5 are 𝟔/𝟑𝟎, 𝟕/𝟑𝟎, 𝟖/𝟑𝟎, 𝟗/𝟑𝟎, 𝟏𝟎/𝟑𝟎
