Answer:
420 people voted
Step-by-step explanation:
First, you need to translate English to math. The winning candidate must have gotten the most number of votes, so this must be the largest number in the ratio, which is 3. You can tell from the ratio that, for every 3 votes the winner received, another candidate got 2, and the final one got just 1. You know that the total number of votes is all the votes these candidates got added together, so you can write this as x = 1/3(210) + 2/3(210) + 210, which you can simplify down to x = 3/3(210) + 210, or just x = 210 + 210. For your final answer, adding these together will get you x = 420. Don't forget your units! (:
