Question 2 (a) Find the quotients: (a) 24.86 ÷ 1.2Now, 24.86 ÷ 1.2 = 24.86/1.2 =24.86 ×1/1.2 Removing decimal point =2486/100 ×1/(12/10) =𝟐𝟒𝟖𝟔/𝟏𝟎𝟎 ×𝟏𝟎/𝟏𝟐 =2486/10 ×1/12 =𝟐𝟒𝟖𝟔/𝟏𝟐 ×𝟏/𝟏𝟎 . =1243/6 ×1/10 =𝟏𝟐𝟒𝟑/𝟔𝟎 Now, we do division like we usually do Thus, 24.86 ÷ 1.2 = 20.71666.. Question 2 (b) Find the quotients: (b) 5.728 ÷ 1.52Now, 5.728 ÷ 1.52 = 5.728/1.52 =5.728 ×1/1.52 Removing decimal point =5728/1000 ×1/(152/100) =𝟓𝟕𝟐𝟖/𝟏𝟎𝟎𝟎 ×𝟏𝟎𝟎/𝟏𝟓𝟐 =5728/10 ×1/152 =𝟓𝟕𝟐𝟖/𝟏𝟓𝟐 ×𝟏/𝟏𝟎 =2864/76 ×1/10 =1432/38 ×1/10 =716/19 ×1/10 =𝟕𝟏𝟔/𝟏𝟗𝟎 Now, we do division like we usually do Thus, 5.728 ÷ 1.52 = 3.76842105…
