FTCE Mathematice Grade 5-9 Practice Test

To understand why the answer is 1.5 liters, it's important to know the relationship between liters and milliliters. One liter is equal to 1,000 milliliters. This means that to convert milliliters to liters, you would divide the number of milliliters by 1,000.

In this case, you have 1,500 milliliters. To convert that to liters:

1,500 milliliters ÷ 1,000 milliliters/liter = 1.5 liters.

Therefore, there are 1.5 liters in 1,500 milliliters, making this the correct answer. This conversion understanding is fundamental in metric system operations and is frequently applied in various mathematical problems involving volume.
