A 3:2 ratio is a way to compare two quantities, showing that for every 3 parts of one quantity, there are 2 parts of another. This ratio can be applied in various contexts, such as in cooking, where a recipe might require 3 cups of flour for every 2 cups of sugar. It helps to maintain the right balance between ingredients. In photography, a 3:2 ratio is commonly used for image dimensions, meaning the width is 1.5 times the height. This aspect ratio is standard for 35mm film and many digital cameras, providing a pleasing composition for photographs.
