## Understanding Ratios

Ratios are a fundamental part of maths and are used in many different areas, including cooking, map reading and even in your favourite video games. If you're curious about how ratios are everywhere in our lives, you're in the right place! Let's explore what ratios are, the terminology used with them and how we can understand them better. Get ready to dive into the world of ratios!

## What is a Ratio?

A ratio is a way to **compare two quantities** by showing **how many times one value contains the other**. It tells us about the **relative size of two quantities**. Think of it like a fruit salad - if a bowl has 2 strawberries and 1 raspberry, we can say the ratio of strawberries to raspberries is 2:1.

### Key Terms in Ratios

Here are some important terms you'll come across when learning about ratios:

Term | Definition |
---|---|

Antecedent | The first number in a ratio |

Consequent | The second number in a ratio |

Equivalent Ratios | Different ratios that express the same relationship |

Proportion | An equation stating that two ratios are equal |

## Examples of Ratios

If a bag has 6 red marbles and 4 blue marbles, the ratio of red to blue marbles is 6:4.

In a classroom with 10 girls and 15 boys, the ratio of girls to boys is 10:15.

## Ratio Language – Different Expressions

Ratios can be expressed in different ways:

- As a fraction: $\frac{1}{2}$
- Using a colon: 1:2
- With the word 'to': 1 to 2

All these expressions mean the same thing - for every 1 of the first quantity, there are 2 of the second quantity.

## Ratio– Application

Answer these questions to test your understanding of ratios and the terms used in ratios.
