What is a ratio?

Back

A ratio is a comparison of two quantities expressed as a fraction, indicating how many times one value contains or is contained within the other.

Front

What are equivalent ratios?

Back

Equivalent ratios are ratios that express the same relationship between two quantities, even if the numbers are different.

Front

How can you represent a ratio?

Back

A ratio can be represented in three ways: as a fraction (e.g., 2/5), with a colon (e.g., 2:5), or with the word 'to' (e.g., 2 to 5).

Front

What is a ratio table?

Back

A ratio table is a table that displays pairs of numbers that form equivalent ratios, helping to visualize the relationship between the quantities.
