Finding the Ratio of Book Price to Number of Pages
In this article, we will explore the concept of finding the ratio of book price to the number of pages for each ordered pair. This involves calculating the price per page for each book and rounding the answer to the nearest hundredth. We will use a table with two columns, one for the number of pages and the other for the price, to make the calculations easier.
We are given a table with the number of pages and the price of each book. Our task is to find the ratio of the price to the number of pages for each ordered pair.
| Number of Pages | Price |
|---|---|
| 200 | 15 |
| 250 | 20 |
| 300 | 25 |
| 350 | 30 |
| 400 | 35 |
To find the ratio of the price to the number of pages, we will divide the price by the number of pages for each ordered pair.
Step 1: Divide the Price by the Number of Pages
We will start by dividing the price by the number of pages for each ordered pair.
| Number of Pages | Price | Ratio |
|---|---|---|
| 200 | 15 | 0.075 |
| 250 | 20 | 0.08 |
| 300 | 25 | 0.0833 |
| 350 | 30 | 0.0857 |
| 400 | 35 | 0.0875 |
Step 2: Round the Answer to the Nearest Hundredth
Next, we will round the answer to the nearest hundredth.
| Number of Pages | Price | Ratio |
|---|---|---|
| 200 | 15 | 0.08 |
| 250 | 20 | 0.08 |
| 300 | 25 | 0.08 |
| 350 | 30 | 0.09 |
| 400 | 35 | 0.09 |
In this article, we found the ratio of book price to the number of pages for each ordered pair. We used a table to make the calculations easier and rounded the answer to the nearest hundredth. The final answer is a table with the number of pages, price, and ratio for each ordered pair.
The ratio of book price to the number of pages can be useful in making purchasing decisions. For example, if two books have the same price but different numbers of pages, the book with the lower ratio may be the better value.
The concept of finding the ratio of book price to the number of pages can be applied to other areas, such as:
- Shopping: When comparing prices of different products, the ratio of price to features can be useful in making purchasing decisions.
- Investing: The ratio of investment returns to risk can be used to evaluate the performance of different investments.
- Science: The ratio of variables in a scientific experiment can be used to analyze the results and draw conclusions.
In conclusion, finding the ratio of book price to the number of pages is a useful skill that can be applied to various areas of life. By using a table to make the calculations easier and rounding the answer to the nearest hundredth, we can make informed decisions and evaluate the value of different products or investments.
Frequently Asked Questions: Finding the Ratio of Book Price to Number of Pages
