Answer 1

You have to make a venn diagram

Answer 2

Ok, first find the number of Juniors
\[Juniors = Total * 0.25\]
This equals to 320 students

THEN, find the number of Juniors who did music or art
\[Music-and-art = Juniors * 0.3\]
This is 96 students

Answer 3

To convert percentage to decimal, do this\[\frac{ percentage }{ 100 }\]
In this instance, \[\frac{ 25}{ 100 }=0.25\]
\[\frac{ 30}{ 100}=0.3\]
