Question

The original version of a song is 3 minutes long. The remix is 25% shorter. How long is the remix?

Answer 1

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

Answer 2

Answer = 2 minutes and 15 seconds

1 minute = 60 seconds

60 seconds times 3= 180 seconds

25% of 180 seconds = 45 seconds

180-45=135 seconds

convert into minutes

1 minute = 60 seconds

2 minutes = 120 seconds

135-120=15 seconds

2 minutes and 15 seconds
