Question

The music for Nadia's dance routine lasts for exactly 4 minutes. When Nadia dances her routine, she starts with her music and finishes 12 seconds before the music ends. What percent of the time the music is playing is Nadia dancing? No algebra plz. Thank you.

Answer 1

Nadia dances to 95% of the music. There are 240 seconds in 4 minutes and .05 or 5% of 240 = 12... therefore the 228 seconds she dances to is 95% of the time,
