Answer:

<h2>Nadia's routine is around 0.95 times the duration of the music.</h2>

Step-by-step explanation:

Givens:

  • The routine last 4 minutes.
  • She finished 12 seconds before the music ends.

Basically, the music is 12 seconds more than the routine, that is, the music last 4 minutes and 12 seconds, which have to transform to just minutes to find the ration between both durations.

12sec\frac{1min}{60sec}=\frac{3}{15}min=\frac{1}{5}min

So, the music is 4\frac{1}{5} min. Now to find the percentage of the music is Nadia's routine, we just have to divide:

4\frac{1}{5} \div 4=\frac{5}{21} \times 4=\frac{20}{21} \approx 0.95

Therefore, Nadia's routine is around 0.95 times the duration of the music.

4 x 60 = 240 seconds

\frac{12}{60} /  \frac{12}{12} =  \frac{1}{5} of a minute not dancing.

4 \times 5 = 20 - 1 = 19\frac{19}{20} \times  \frac{5}{5} =  \frac{95}{100}

95% of the time dancing
