Sure! Let's go through the problem step by step.
1. First, we know that 1 gallon is approximately equal to 3.8 liters. This is our conversion factor.
2. Since we have 15 gallons, we need to convert these gallons to liters. We can do this by multiplying the number of gallons by the conversion factor.
\(\( 15 \text{ gallons} \times 3.8 \text{ liters/gallon} \)\)
3. Carrying out the multiplication:
\(\( 15 \times 3.8 = 57 \)\)
4. So, 15 gallons is equal to 57 liters.
5. Lastly, we need to round this result to the nearest tenth. In this case, 57 is already a whole number and thus, when rounding to the nearest tenth, it remains 57.0.
Therefore, 15 gallons is approximately 57.0 liters when rounded to the nearest tenth.
