A 1:1 ratio means that two quantities are equal. For example, if you have one apple and one orange, the ratio of apples to oranges is 1:1. This indicates that for every apple, there is one orange, showing a perfect balance between the two items. In various fields, such as cooking or finance, a 1:1 ratio can be important for achieving desired results. For instance, when mixing ingredients, a 1:1 ratio of water to flour ensures the right consistency for a batter. Similarly, in budgeting, a 1:1 ratio of income to expenses helps maintain financial stability.
