a percentage question, answer if you know, please. :)

For this case we have that[tex]\frac {1} {4}[/tex]of the songs are jazz.
The total songs are 100.
So:
[tex]\frac {1} {4} = 0.25\\\frac {3} {4} = 0.75[/tex]
This tells us that 25% of the songs are jazz and 75% of the songs are pop.
[tex]\frac {1} {4} + \frac {3} {4} = \frac {4} {4} = 1[/tex]
So, the correct option is option D.
Answer:
Option D
