Since 1 rupee = 50 paise, then
2 rupee = 2 x 50 = 100 paise
Now, we can find the ratio between 50 p: 100 p
[tex]50\colon100[/tex]Divide both terms by 10
[tex]\frac{50}{10}\colon\frac{100}{10}=5\colon10[/tex]Divide both terms by 5
[tex]\frac{5}{5}\colon\frac{10}{5}=1\colon2[/tex]The ratio between 50 p: 2 rupee = 1: 2
