How to solve unit rate problems A ratio is a comparison of two numbers or measurements. The objects being compared are called the terms of the ratio. If the two terms are in different units this is called a rate. For example, if a 12-ounce coke costs 84¢, the rate is 84¢ for 12 ounces. The ratio has cents and ounces You can write this rate as a fraction 84¢/12 ounces or 84¢:12 ounces. Both expressions mean that you pay 84¢ "for every" 12 ounces of coke.
