Question 3(b) – Page 174 Write the following fractions in descending order. (b) 3/4, 12/5 , 7/12 , 5/4 So, to find common denominator of these fractions We need to find LCM Common denominator = LCM of 4, 5, 12, 4 = 2 × 2 × 3 × 5 = 60 Now, making denominator 60 of all these fractions 𝟑/𝟒=𝟑/𝟒 ×𝟏𝟓/𝟏𝟓 =𝟒𝟓/𝟔𝟎 𝟏𝟐/𝟓=𝟏𝟐/𝟓 ×𝟏𝟐/𝟏𝟐 =𝟏𝟒𝟒/𝟔𝟎 𝟕/𝟏𝟐=𝟕/𝟏𝟐 ×𝟓/𝟓 =𝟑𝟓/𝟔𝟎 𝟓/𝟒=𝟓/𝟒 ×𝟏𝟓/𝟏𝟓 =𝟕𝟓/𝟔𝟎 Writing in descending order 𝟏𝟒𝟒/𝟔𝟎>𝟕𝟓/𝟔𝟎>𝟒𝟓/𝟔𝟎>𝟑𝟓/𝟔𝟎 Or we can write 𝟏𝟐/𝟓>𝟓/𝟒>𝟑/𝟒>𝟕/𝟏𝟐
