[tex]\dfrac{2}{5}[/tex]
and on multiplying the fraction with 100 we get the percent of songs.
Hence,
[tex]\dfrac{2}{5}\times 100=40\%[/tex]
- The fraction of songs which are country songs are:
[tex]\dfrac{15}{50}[/tex]

[tex]\dfrac{3}{10}[/tex]
Hence,
[tex]\dfrac{3}{10}\times 100=30\%[/tex]
- The fraction of songs which are world songs are:
[tex]\dfrac{10}{50}[/tex]
which in simplest fraction is given by:
[tex]\dfrac{1}{5}[/tex]
Hence,
[tex]\dfrac{1}{5}\times 100=20\%[/tex]
- The fraction of songs which are classical songs are:
[tex]\dfrac{5}{50}[/tex]
which in simplest fraction is given by:
[tex]\dfrac{1}{10}[/tex]
Hence,
[tex]\dfrac{1}{10}\times 100=10\%[/tex]
