What is Ratio?

What is percentage?
The percentage is defined as the ratio expressed as a fraction of 100.The percentage is denoted by sign of %.For example, if XYZ scored 46% marks in his test, it means that he scored 46 marks out of 100. It is written as 46/100 in the fraction form and 46:100 in terms of ratio.
Given that 10% of m =20% of n
⇒ m × 10/100 = n × 20/100
⇒ m/n = (20/100)×(100/10)
⇒ m/n = (2/10)×(10/1)
⇒ m/n = 2/1
⇒ m : n = 2 : 1
Hence, the ratio of m and n is 2 : 1
