A ratio of 1:25 means that for every 1 unit of one quantity, there are 25 units of another quantity. This can be applied in various contexts, such as mixing ingredients in a recipe or comparing sizes. For example, if you have 1 cup of sugar, you would need 25 cups of flour to maintain that ratio. In practical terms, a 1:25 ratio can also represent a scale or proportion. In maps, a 1:25 ratio indicates that 1 unit on the map equals 25 units in real life. Understanding ratios helps in making comparisons and calculations in everyday situations.
