Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

![On this educational page, we focus on understanding ratios and unit rates with practical examples.
### Ratios
Let's begin with some examples of ratios:
**Examples:**
- 7. 3:1
- 10. 7:4
### Unit Rates
Next, let's learn how to find the unit rate from given data.
**Examples:**
13. Find the unit rate for $36 in 4 hours.
\[ \frac{\$36}{4 \, \text{h}} = \, \]
16. Find the unit rate for 300 words in 5 minutes.
\[ \frac{300 \, \text{words}}{5 \, \text{min}} = \, \]
19. Find the unit rate for 288 bottles in 12 cases.
\[ \frac{288 \, \text{bottles}}{12 \, \text{cases}} = \, \]
### Exercises
Try finding the unit rates for each of the examples above, and check your answers with the solutions provided at the bottom of the page. Understanding how to calculate and interpret unit rates will help in a variety of real-world scenarios, from budgeting to time management.
We hope this page helps clarify the concept of ratios and unit rates. Happy learning!](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0430c712-8742-4dc1-92bc-b9a5e9a9288b%2F2ffe2181-6fae-4a32-aea7-5e4794705cd3%2F50pjkkk_reoriented.jpeg&w=3840&q=75)
