Visual aids can really help us understand percentages and ratios better. Here are some helpful methods:

1. Bar Graphs: These show percentages in a way that's easy to see. For example, you can see 25% as a fourth of a bar.

2. Pie Charts: These round charts show how parts relate to the whole. They help us understand ratios in a clear way.

3. Ratio Tables: These are great for displaying equal ratios and percentages. They keep everything organized.

4. Percent Models: Think of grids where each square stands for 1%. If you fill 60 squares, that represents 60%.

Using these tools can make it clear how a ratio like $2:3$ connects to percentages. One part is $40\%$ and the other is $60\%$.
