A ratio compares two quantities having the same units. It is written using a colon ‘:’, for example, 2:3, and is also written in fraction form as 23. For example, the expression between 20kg of sugar and 14 kg of wheat represents a ratio.
A rateis a unique ratio that compares 2 quantities with different units. For example, if a man covers 3 km in 30 minutes, it is written as 3 km/30 minutes. A unit rate is a rate with a denominator of 1. Let us use the concept of ratios and rates to solve some problems.
Ratio and rates are frequently used together in our everyday life for comparing two quantities. While calculating the amount to be paid to a shopkeeper to the amount of return we will get back, all involves calculating rates of quantities in the form of ratio. They are also used to calculate the birth, mortality or death rate of a population. The r...
Learn what rate means in mathematics and see how to compare two related quantities using different units. Find examples of rate in pancakes, sausages, interest and more.
A rate is a ratio that compares two different quantities that have different units of measure. A rate is a comparison that provides information such as dollars per hour, feet per second, miles per hour, and dollars per quart, for example.
Learn the definitions and examples of ratios and rates, and how to compare pure and denominate numbers by subtraction and division. See exercises and practice problems on comparing quantities and units.
A rate may be equivalently expressed as an inverse of its value if the ratio of its units is also inverse. For example, 5 miles (mi) per kilowatt-hour (kWh) corresponds to 1/5 kWh/mi (or 200 Wh/mi). Rates are relevant to many aspects of everyday life. For example: How fast are you driving?
