7 liters is the same as how many gallons?
Hint: 1 L \approx 0.26 gal
Round your answer to the nearest tenth.
The Correct Answer and Explanation is:
To solve the question:
“7 liters is the same as how many gallons?”
Given: 1 liter ≈ 0.26 gallons
Step-by-Step Solution:
To convert 7 liters to gallons using the given conversion factor:7 liters×0.26 gallonsliter=1.82 gallons7 \, \text{liters} \times 0.26 \, \frac{\text{gallons}}{\text{liter}} = 1.82 \, \text{gallons}7liters×0.26litergallons=1.82gallons
Now, round 1.82 to the nearest tenth:1.82≈1.81.82 \approx 1.81.82≈1.8
✅ Final Answer: 1.8 gallons
📘 Explanation
This problem involves a simple unit conversion from liters (L) to gallons (gal). Unit conversions are important in real-life contexts like cooking, fuel measurements, and scientific calculations. The key to solving such problems is understanding the conversion factor, which is a ratio that shows the relationship between two units of measurement.
In this case, we are told that 1 liter is approximately equal to 0.26 gallons. This means that for every liter of liquid, there are about 0.26 gallons. So, if we have 7 liters, we multiply 7 by 0.26 to find out how many gallons this is. The multiplication looks like this:7×0.26=1.827 \times 0.26 = 1.827×0.26=1.82
The result, 1.82, tells us that 7 liters is about 1.82 gallons. However, the question specifically asks us to round the answer to the nearest tenth. To round a number to the nearest tenth, we look at the digit in the hundredths place (the second digit after the decimal point). If it’s 5 or more, we round up. If it’s 4 or less, we round down.
In 1.82, the hundredths digit is 2, which is less than 5. So we round down, and 1.82 becomes 1.8.
This conversion process shows how essential basic math skills are for interpreting measurements across different systems, like the metric system (liters) and the U.S. customary system (gallons).
