Express the given Roman numerals in English numerals:

 (i) VI = 5 + 1 = 6 So, VI = 6 (iii) XXIX = 10 + 10 + (10 - 1) = 29 So, XXIX = 29 (v) XXXIX = 10 + 10 + 10 + (10 - 1) = 39 So, XXXIX = 39 (vii) XVI = 10 + 5 + 1 = 16 So, XVI = 16 (ii) XVII = 10 + 5 + 2 = 17 So, XVII = 17 (iv) XXVIII = 10 + 10 + 5 + 3 = 28So, XXVIII = 28 (vi) XXIV = 10 + 10 + (5 - 1) = 24 So, XXIV = 24 (viii) XXV = 10 + 10 + 5 = 25 So, XXV = 25
