A "1:10 ratio" means that for every one part of something, there are ten parts of another. This can be applied in various contexts, such as mixing ingredients, financial investments, or comparing sizes. For example, if you have 1 cup of sugar and want to maintain a 1:10 ratio with water, you would need 10 cups of water. In a business context, a 1:10 ratio might refer to the relationship between revenue and expenses. If a company earns $1 in revenue for every $10 spent, it indicates a significant investment compared to income. Understanding ratios helps in making informed decisions in both personal and professional settings.
