Answer:
2 mins 15 secs
Step-by-step explanation:
If the original version of the song is 100% in length, then the remix will be 75% of the length of the original, as:
100% - 25% = 75%
Convert 75% into a decimal:
⇒ 75% = 75/100 = 0.75
75% of 3 minutes
= 0.75 × 3
= 2.25 minutes
As there are 60 seconds in a minute,
= 0.25 of a minute = 0.25 × 60 = 15 seconds
Therefore, the length of the remix is 2 mins 15 secs
