Simplifying Ratios: Key Concepts and Examples

The video tutorial by Mr. J explains how to simplify ratios by finding the greatest common factor, similar to simplifying fractions. It covers two examples: simplifying the ratios 9 to 21 and 30 to 6, demonstrating different methods and emphasizing that a simplified ratio maintains the same relationship as the original. The tutorial concludes with tips on recognizing when a ratio is already in its simplest form.

What is the first step in simplifying a ratio?

• Divide by the smallest number

• Multiply both terms by the same number

• Identify and divide by the greatest common factor

• Convert the ratio to a decimal

What does simplifying a ratio change?

• Its numerical form only

• Nothing, it remains equivalent

• Its comparison or relationship

• Its value

Can a ratio be in its simplest form from the start?

• Yes, if the greatest common factor is one

• No, all ratios can be simplified further

• Yes, if it is a prime number

• No, simplification requires division by two
