And of course, when we’re shopping, the better deal means the lower price. So since All-mart is 0.75 per can, that means that All-mart is the better deal because it has a lower unit price. So as a fraction, that’s $3 over four cans keeping the money at the numerator. Three divided by four will equal zero point 75 or seventy five cents per can.
Some other examples include walking for 30 minutes per day, reading 20 pages per hour. Now, let’s consider another example involving comparing running speeds. Jalen can run 60 meters in 9 seconds, and Kayla can run 80 meters in 12 seconds. We’ll use ratios and unit rates to compare their speeds and determine the faster runner. For another example, suppose you paid 120 dollars for a car you rented for 3 days.
What is the formula for getting the unit price?
You pay more money for the larger container of blueberries, but you also get more blueberries than you would with the smaller container. Put simply, the container on the right is a better value than the container on the left. You may have noticed that grocery shelves are marked with the unit price (as well as the total price) of each product. This unit price makes it easy for shoppers to compare the prices of competing brands and different package sizes. A common way to write this unit rate is 60 miles per hour.
As the number of people increases the cost each person pays will decrease. If you divide the number of people by 3, the time taken must be multiplied by 3 as the two values are inversely proportional. You need to calculate the number of kilometers for 23 miles, so you need to multiply 1.6 by 23. As 5 miles is approximately 8 kilometers, you divide the number of kilometers by 5 to find the number of kilometers per mile. This fraction means that the rate of buses to people is 6 to 300 or, simplified, 1 bus for every 50 people. Often, one quantity in the ratio is greater than the second quantity.
In this video lesson, we learned that when comparing values, setting up ratios as fractions and converting them to unit rates or unit prices is a valuable method. This approach enables us to make informed decisions when determining the better deal, faster runner, or any other comparative scenario presented in word problems. A rate is a ratio that compares two different quantities that have different units of measure.

The rate of miles per minute gives the distance traveled per unit of time. The unit rate is 40 kilometers per hour or 40 kph.( b ) There are 200 students and 5 teachers. The unit rate is 40 students per teacher or 40 students/teacher.( c ) A gardener earned 520 dollars in 40 hours of work.
Despite its importance, unit price information is often overlooked in online stores due to technical and design limitations. Many retailers struggle to integrate price per unit effectively, leading to inconsistencies that reduce usability. Lack of pricing clarity can create doubt, making shoppers question whether they are getting a fair deal, or lead to incorrect assumptions. With unit prices, retailers provide transparent pricing that helps consumers make informed choices with confidence.
A conversion of either miles to kilometers or kilometers to miles must be made to make a fair comparison of average speed. Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity. Therefore, a unit rate can express be like 60 seconds per minute. Unit price calculation is straightforward, yet businesses often neglect to provide this information in a user-friendly format. The basic formula to find the price per unit is to divide the total price by the total quantity.
- A rate is a ratio that compares two different quantities that have different units of measure.
- Many retailers struggle to integrate price per unit effectively, leading to inconsistencies that reduce usability.
- The unit rate is 74 heartbeats per minute or 74 heartbeats/minute.( f ) A sprinter runs 120 meters in 20 seconds.
- Without unit pricing, shoppers may struggle to determine the best value, leading to frustration and lost sales.
- This fraction means that the rate of buses to people is 6 to 300 or, simplified, 1 bus for every 50 people.
If a car travels 24 miles in 2 hours, calculate the average speed of the car. Ratio and rates are frequently used together in everyday life to compare two quantities. While calculating the amount to be paid to shopkeepers to the changes, we will get back; all involve calculating rates of quantities in the form of a ratio. Consumers expect pricing transparency, especially when comparing product variations, bulk deals, or subscription options.
You can find out how much x pens cost by multiplying 20 by the number of pens, x.
For example, if we say that a car travels at a speed of 100 miles per hour, then it means in one hour it covers 100 miles. This way of comparing two different units expressed as a single ratio is termed as ‘Rate’. A very common example of a unit rate, which we encounter on a daily basis, is miles per hour. Since this rate is describing the number of miles in one hour, it is a unit rate. Another common unit rate is the price of gas per gallon.
Practice Questions on Rate Definition
- Let’s look at the details of the lesson using examples of comparing prices and determining the faster runner.
- With unit prices, retailers provide transparent pricing that helps consumers make informed choices with confidence.
- Find the unit rate if a worker earns $800 in 40 hours.
- So that tells us that at Super Shopper it’s ninety cents per can.
To calculate the unit cost, let us divide the total cost of 320 dollars by the total units in 3 days. For example, suppose you paid 120 dollars for a car you rented for 3 days. Rates are a special type of ratio used to describe a relationship between different units of measure, such as speed, wages, or prices. A car can be described as traveling 60 miles per hour; a landscaper might earn $35 per lawn mowed; gas may be sold at $3 per gallon. An example of unit rate is 50 miles per hour, which means 50 miles are covered in one hour, whereas, 1000 miles/10 hours, is an example of rate and not unit rate.
Unit Rate Problems
If you’re operating in regulated markets, you must ensure compliance with unit pricing laws. Regions such as the EU, Australia, and parts of the U.S. and Canada require retailers to display unit prices for certain products. Unit price is the cost of a unit of a product per standard unit of measurement (weight or volume), such as per liter, per ounce, or per kilogram. This pricing model allows consumers to compare the cost of different products based on value rather than just total price. Two quantities in different units are compared using a rate, while A ratio is a comparison of two quantities or numbers expressed in the same a unit price is a ratio that compares units.
In this article, we will have the definition of rate, unit rate, and unit price and some solved examples in calculating unit rates. We do not actually calculate rate; rate is a ratio between two things that have different units of measure. For example, if we know that a pack of 3 Romaine Hearts costs $2.99, then the rate is $2.99/pack of Romaine Hearts. Rates are spoken about and used every day in many aspects of life. The concept is pretty straightforward, as rates are nothing more than ratios of values that represent different units of measure. The values that are being compared are called the terms of the rate.
A unit rate is a ratio between 2 distinct units with one as the denominator. A rate and a unit rate are two different ways to compare two separate units of measurement. A rate is a ratio between two different units, whereas a unit rate is the comparison of two different units of measurement with a denominator of 1. The cost of a single item is expressed as a unit price.
1.1: Simplifying Ratios and Rates
Unit rate allows for easy comparison between data values. Unit rates are frequently employed in practical situations, such as when converting between measurement systems. You can write the ratio using words, a fraction, and also using a colon as shown below.
