In a recent student government election, the ratio of students who voted for the winner to all the students who voted was 0.55 The number of students who voted was 40. How many votes did the winner get?
The ratio being 0.55 means 55% of students voted for the person who ended up winning. If there were 40 people who voted, just find 55% of 40. This is done by 0.55 • 40, which equals 22. So 22 students voted for the person who ended up winning.
