Final answer:
Finding a unit rate with a fraction is similar to with whole numbers, requiring you to find the per-one-unit rate. However, additional steps are needed when fractions are involved, such as simplifying or finding a common denominator. This process is essential for unit conversions and comparing measurements.
Step-by-step explanation:
Finding a unit rate when one of the quantities is a fraction is similar to when both quantities are whole numbers because in both cases, you are seeking a ratio that compares two measurements where one of those measurements is 1. The process involves dividing the two quantities to find the rate per one unit. However, when working with fractions, you must perform additional steps such as finding a common denominator or simplifying fractions to find the unit rate.
For example, for a unit rate such as 55 miles per hour, which can be expressed as 55/1 miles per hour, the quantity of time (hours) is already 1, so the rate is clear. When a fraction is involved, you might have something like a 1/2 inch on a map representing 100 feet. To find the unit rate, you would express the ratio as 0.5/100 and then simplify.
