Respuesta :
1/5 is one out of the 5 parts of the song. Now you need to multiply 1/15 by 5/1. This will give you 5/15 or 1/3 of a minute. It will take him 20 seconds to play the entire song.
Answer: [tex]\dfrac{1}{3}[/tex] of a minute.
Step-by-step explanation:
Given : The time taken to play [tex]\dfrac{1}{5}[/tex] of a song = [tex]\dfrac{1}{15}[/tex] of a minute.
Then , The time taken to play an entire song will be : [tex]5\times\dfrac{1}{15}[/tex] of a minute.
i.e. The time taken to play an entire song will be : [tex]\dfrac{1}{3}[/tex] of a minute.
Hence, it will take [tex]\dfrac{1}{3}[/tex] of a minute to play the entire song.
