Convert 80 liters into gallons. Round your answer to the nearest tenth.
The correct answer and explanation is:
To convert liters to gallons, use the conversion factor:
1 liter = 0.264172 gallons.
Given that you have 80 liters, you can calculate the equivalent in gallons by multiplying 80 by 0.264172. 80 liters×0.264172 gallons/liter=21.13 gallons.80 \, \text{liters} \times 0.264172 \, \text{gallons/liter} = 21.13 \, \text{gallons}.
Thus, 80 liters is approximately 21.1 gallons, when rounded to the nearest tenth.
Explanation:
The liter is a metric unit of volume, while the gallon is a unit used mainly in the United States to measure liquid volumes. To convert between these units, we need to know the appropriate conversion factor. The most common conversion factor between liters and US gallons is approximately 0.264172. This factor comes from the difference in how both measurement systems define their units of volume.
The process of conversion is simple:
- Identify the amount in liters that needs to be converted.
- Multiply the given liters by the conversion factor to get gallons.
- Round the result to the nearest desired decimal place, if necessary.
In this case, you multiply 80 liters by 0.264172, and the result is 21.13776 gallons. When rounded to the nearest tenth, this value becomes 21.1 gallons.
Understanding the conversion between liters and gallons is useful in many real-world situations, like cooking, driving (fuel consumption), or when measuring liquids in scientific or industrial settings. It’s important to always check whether you’re dealing with US gallons, imperial gallons, or other types of gallons, as the conversion factor can slightly vary depending on the system being used.
