1. Define Scale Factor
A scale factor is a ratio that compares the size of an object or image to its original size. It is expressed as a fraction or decimal and is used to enlarge or reduce an object or image proportionally.
For example, if the scale factor is 2, the new object or image will be twice the size of the original. If the scale factor is 0.5, the new object or image will be half the size of the original.
2. Scale Factor in Word Problems: Scale Factor Word Problems Worksheet
Scale factor is often used in word problems to determine the dimensions of an enlarged or reduced object or image.
| Original Measurement | Scale Factor | Scaled Measurement |
|---|---|---|
| 5 cm | 2 | 10 cm |
| 10 m | 0.5 | 5 m |
| 15 in | 1.5 | 22.5 in |
For example, if a painting is originally 10 cm wide and you want to enlarge it by a scale factor of 2, the new painting will be 20 cm wide.
3. Types of Scale Factor Problems
There are three main types of scale factor problems:
- Enlargement problems:In these problems, the new object or image is larger than the original.
- Reduction problems:In these problems, the new object or image is smaller than the original.
- Mixed problems:In these problems, the new object or image is both enlarged and reduced.
Each type of problem has its own strategy for solving.
4. Applications of Scale Factor
Scale factor is used in a variety of fields, including:
| Field | Application | Example |
|---|---|---|
| Architecture | Creating blueprints and scale models | A blueprint of a house might be drawn at a scale of 1:100, meaning that 1 cm on the blueprint represents 100 cm in the actual house. |
| Engineering | Designing bridges and other structures | An engineer might use a scale factor to determine the forces acting on a bridge. |
| Cartography | Creating maps | A map might be drawn at a scale of 1:24,000, meaning that 1 cm on the map represents 24,000 cm in the actual area. |
