How many mL are in 3/4 of a liter?

To determine how many milliliters are in 3/4 of a liter, it's important to recognize the conversions between liters and milliliters. One liter is equivalent to 1,000 milliliters. Therefore, to find 3/4 of a liter in milliliters, you simply multiply the total number of milliliters in a liter by the fraction:

1 liter = 1,000 mL

3/4 of a liter = (3/4) × 1,000 mL = 750 mL

This calculation clearly leads to the conclusion that 3/4 of a liter amounts to 750 milliliters. Thus, the correct choice reflects this conversion accurately. Understanding how to convert between these two units is crucial in medication math, as medication dosages are often expressed in milliliters, and calculations must be precise to ensure patient safety.
