To find the unit rate of a question, you need to divide the quantity of one unit by the corresponding quantity of another unit. Here's a step-by-step guide on how to do it:
1. Determine the given quantities: Identify the values provided in the question that involve different units. For example, if the question provides the distance in miles and the time in hours, you have two different units: miles and hours.
2. Identify the numerator and denominator: Determine which quantity will be the numerator (top) and which will be the denominator (bottom) of your unit rate. In this example, distance (miles) will be the numerator and time (hours) will be the denominator.
3. Calculate the unit rate: Divide the numerator by the denominator to obtain the unit rate. For example, if the question provides a distance of 100 miles and a time of 2 hours, you would divide 100 by 2: 100 miles รท 2 hours = 50 miles per hour.
4. Express the unit rate: Write the unit rate in a specific format, typically "X per Y." In our example, the unit rate would be expressed as 50 miles per hour.
Remember that the unit rate represents the amount of one unit in relation to another unit, usually indicating a ratio or rate of change.
To find the unit rate of a question, follow these steps:
1. Read the question carefully and identify the given quantities. For example, if the question is about distance and time, determine the values of distance and time mentioned.
2. Determine which quantity should be used as the numerator (top) of the unit rate. For example, if you want to find the unit rate of speed, the distance covered should be the numerator.
3. Identify the corresponding unit for the numerator. For distance, it could be kilometers (km) or miles (mi).
4. Determine the unit for the denominator (bottom) of the unit rate. For speed, the unit of time, such as hours (hr) or minutes (min), should be used.
5. Calculate the value of the numerator and denominator. If the given quantities are in different units, convert them to the same unit before proceeding.
6. Divide the numerator by the denominator to obtain the unit rate. Make sure to write the unit for the unit rate, as it represents the amount per one unit of the denominator.
7. Include the appropriate numerator unit in the answer. If the unit rate is 50 km/h, for instance, it means the object is moving at a rate of 50 kilometers per hour.
Remember to double-check your work and ensure you correctly interpret the meaning of the given quantities and units for the question at hand.
