Question

You have 9.24 gigabytes available on your MP3 player. Each song is about 0.022 gigabyte. How many songs can you download onto your MP3 player?

Answer 1

Answer: 420 songs

Work Shown:

x = number of songs

1 song = 0.022 GB

x songs = 0.022x GB .... multiply both sides by x

0.022x = 9.24

x = 9.24/0.022 ..... divide both sides by 0.022

x = 420
