  1. Chapter 9 Class 7 Rational Numbers
  2. Serial order wise


Example 3 Do 4/(โˆ’9) and (โˆ’16)/36 represent the same rational number? Here, we write both numbers in standard form. ๐Ÿ’/(โˆ’๐Ÿ—) 4/(โˆ’9) = (โˆ’4)/9 (โˆ’๐Ÿ๐Ÿ”)/๐Ÿ‘๐Ÿ” (โˆ’16)/36 = (โˆ’16)/36 = (โˆ’8)/18 = (โˆ’4)/9 Since both numbers are (โˆ’4)/9 They are same.
