Willa downloads 5 songs. three of the song files are each 2.75mb. two song files are each 3.8 mb. how much space does willa need for the songs she downloads?

2.75X3= 8.25 MB
3.8X2= 7.6 MB
8.25+7.6= 15.85 MB

Well lets do the work, she wants 5 songs. So let's Multiply  

The first three songs she wants are 2.75 each and she wants three so, 2.75 x 3 = 8.25 MB

The second two songs she wants are 3.8 MB each so 3.8 x 2 = 7.6 MB

So let's add the total of those list of songs, 7.6 + 8.25 = 15.85

So your answer is 15.85 MB is what she needs (: 

The answer that i got was 8/3
