The baseball team voted on what they wanted to eat after the game
so, total number of players =30
pizza vote =8
chicken vote=12

so, sum of all votes must be 30
we get
pizza vote + chicken vote + hamburgers vote= total number of vote
we can plug values


So,
hamburgers vote=10
now, we have to find the ratio of votes for pizza to hamburgers
so, we get

now, we can simplify it


So,
the ratio of votes for pizza to hamburgers is
