Identifying the Given Information
Successfully tackling unit rate problems from resources like Mathworksheetsland;com begins with carefully dissecting the problem statement․ The first crucial step is pinpointing the two quantities being compared․ For example, in a problem stating “A 9-kg bag of mangoes for $12,” the quantities are kilograms (kg) and dollars ($)․
Next, determine which quantity is the dependent variable – the one you’re trying to find the rate for․ Often, this is expressed as “per” something else․ In our mango example, we want to find the cost per kilogram․
Accurately identifying these values – the total quantity of each item and the total cost or measurement – is paramount․ Look for keywords like “for,” “in,” or “per” to help distinguish the quantities․ Ensure you understand the units associated with each value (e․g․, kg, miles, hours, words, minutes)․ Misidentifying the given information will inevitably lead to an incorrect solution․ Double-checking these initial values is a worthwhile investment of time․
Setting up the Proportion
Once you’ve identified the given information from a unit rate worksheet (like those on Mathworksheetsland․com), the next step is constructing a proportion․ A proportion is an equation stating two ratios are equal․ For instance, if a 9-kg bag of mangoes costs $12, we can set up the proportion: 9 kg / $12 = 1 kg / $x, where ‘x’ represents the cost of 1 kg (the unit rate)․
The key is to ensure the units align correctly․ Place the quantities of the same type in the numerators or denominators․ Consistency is vital․ Alternatively, you can express it as $12 / 9 kg = $x / 1 kg․
This proportional setup reflects the core concept of unit rates: finding the value of one unit․ Remember, the order of the ratios must be consistent to maintain equality․ A correctly formed proportion is the foundation for accurately solving for the unit rate․
Solving for the Unit Rate
After setting up the proportion – for example, 9 kg / $12 = 1 kg / $x – solving for the unit rate involves cross-multiplication․ This means multiplying the numerator of the first ratio by the denominator of the second, and vice versa․ So, 9 kg * $x = $12 * 1 kg․
This simplifies to 9x = 12․ To isolate ‘x’ (the unit rate), divide both sides of the equation by 9: x = 12 / 9․ This results in x = 1․33 (rounded to two decimal places)․ Therefore, the unit rate is $1․33 per kg․
Applying this to Mathworksheetsland․com’s examples, like 725 miles in 8 hours, the proportion becomes 725 miles / 8 hours = x miles / 1 hour, leading to x = 90․6 miles per hour․ Always include the correct units in your final answer!
