Step: Express the ratio in simplest form
Since 1 rupee =100 paise,
Therefore,
10 paise :1 rupee =10 paise100 paise
Above ratio or fraction can be converted to its simplest form by dividing numerator and denominator by their HCF equal to 10, we get,
10100=10÷10100÷10=110
Hence, the simplest form of the given ratio is 1 :10.
