Simpler Version:
Title Slide:
- Introduction to Ratios
Slide 1:
- Definition of Ratio: A ratio is a comparison of two or more quantities.
Slide 2:
- Writing Ratios: Ratios can be written using the word “to,” a colon (:), or a fraction.
Slide 3:
- Example: If there are 5 red apples and 3 green apples, the ratio of red apples to green apples can be written as 5:3, 5 to 3, or 5/3.
Slide 4:
- Simplifying Ratios: Ratios can be simplified by dividing both sides by their greatest common factor (GCF).
Slide 5:
- Example: If the ratio is 12:8, the GCF is 4. Dividing both sides by 4 gives us the simplified ratio of 3:2.
Slide 6:
- Equivalent Ratios: Ratios that represent the same comparison are called equivalent ratios. They can be found by multiplying or dividing both sides of a ratio by the same number.
Slide 7:
- Example: If the ratio is 2:3, multiplying both sides by 2 gives us the equivalent ratio of 4:6.
Slide 8:
- Summary: Recap the main points about ratios and their importance in comparing quantities.

Title Slide:
- Introduction to Ratios
Slide 1:
- Definition of Ratio: A ratio is a comparison of two or more quantities. It shows how much one quantity is in relation to another.
Slide 2:
- Writing Ratios: Ratios can be written in three different ways: using the word “to,” using a colon (:), or using a fraction.
Slide 3:
- Example: If there are 5 red apples and 3 green apples, the ratio of red apples to green apples can be written as 5:3, 5 to 3, or 5/3.
Slide 4:
- Simplifying Ratios: Ratios can be simplified by dividing both sides by their greatest common factor (GCF).
Slide 5:
- Example: If the ratio is 12:8, the GCF is 4. Dividing both sides by 4 gives us the simplified ratio of 3:2.
Slide 6:
- Equivalent Ratios: Ratios that represent the same comparison are called equivalent ratios. They can be found by multiplying or dividing both sides of a ratio by the same number.
Slide 7:
- Example: If the ratio is 2:3, multiplying both sides by 2 gives us the equivalent ratio of 4:6.
Slide 8:
- Proportions: A proportion is an equation that states two ratios are equal. It can be solved using cross-multiplication.
Slide 9:
- Example: If the proportion is 2/3 = x/9, cross-multiplying gives us 2 * 9 = 3 * x. Solving for x, we get x = 6.
Slide 10:
- Using Ratios in Real Life: Ratios are used in various real-life situations, such as cooking recipes, map scales, and financial planning.
Slide 11:
- Summary: Recap the main points about ratios and their importance in comparing quantities.
Slide 12:
- Additional Resources: Provide links or references to additional resources or websites where students can further explore ratios.
Slide 13:
- Q&A: Allow students to ask any questions they may have about ratios or the content covered in the presentation.
Slide 14:
- Thank You: Conclude the presentation with a thank you slide and any final remarks or reminders.

Slide 11:
- Proportional Relationships: Ratios can represent proportional relationships, where the ratio remains constant as the quantities change.
Slide 12:
- Example: If the ratio of boys to girls in a class is 3:5, and there are 24 boys, we can find the number of girls by setting up a proportion.
Slide 13:
- Example: 3/5 = 24/x. Cross-multiplying gives us 3x = 5 * 24. Solving for x, we get x = 40.
