Final answer:
To convert 1.5 gallons to milliliters, multiply 1.5 by 3.785 to get liters, then multiply by 1,000 to get milliliters, which equals 5,677.5 milliliters.
Step-by-step explanation:
The question asks how to convert 1.5 gallons of water into milliliters. To solve this, we will first convert gallons to liters, and then convert liters to milliliters. One gallon is equal to approximately 3.785 liters. So, we need to multiply 1.5 by 3.785 to convert gallons to liters.
1.5 gallons × 3.785 liters/gallon = 5.6775 liters.
Now, since 1 liter is equivalent to 1,000 milliliters, we can find the amount in milliliters by multiplying the value in liters by 1,000.
5.6775 liters × 1,000 milliliters/liter = 5,677.5 milliliters.
Therefore, 1.5 gallons of water is equal to 5,677.5 milliliters.
