Answer: 2171 millimeter
Explanation:
From the question, we are informed that Ming's science beaker contains 2 liters of water and that Kelly added 26 milliliters of liquid coloring while Ryan added another 145 milliliters of liquid soap.
The milliliters of liquid that are in Ming's beaker now will be:
= 2 liters + 26 millimeters + 145 millimeters
= 2000 + 26 + 145
= 2171 millimeter
Note that 1000 millimeter = 1 liter
