The city council voted on a new tax. 18 council members voted in favor of the tax. The council has 90 members. What percentage of the council members voted in favor of the tax?
Answer: 20% Explanation: You can set up a ratio. 18 / 90 to x / 100. x is the percentage of a full 100. Cross multiply, which gives you 1800 and 90. Divide, which gives you 20.
