This calculator helps you determine the unit rate when dealing with quantities expressed as fractions. Unit rate is a ratio that compares two different units, such as 'miles per hour' or 'dollars per pound'. When working with fractions, this calculator simplifies the process of finding out how much of one quantity you get for one unit of another quantity.
