Answer 2

i)    HCF = 1

      ∴Lowest form of 57/190 = 57/190 itself

ii)   HCF = 6

      36/420 = 36÷12 / 420÷12

                    = 3/35

       ∴Lowest form of 36/420 = 3/35

iii)  HCF

       216/144 =   216 ÷ 72 / 144 ÷ 72

                       =  3/2

      ∴Lowest form of  216/144 = 3/2
