If a patient weighs 110 pounds, how many kilograms do they weigh? Please round to the nearest whole number and show your work.

50 kilograms. 110 pounds / 2.2 pounds/kilogram = 50 kilograms

A doctor orders 6 fluid ounces of medication. How many milliliters is that?

180 milliliters. 6 fluid ounces * 30 milliliters/fluid ounce = 180 milliliters

5 teaspoons. 25 milliliters / 5 milliliters/teaspoon = 5 teaspoons

90 milliliters. 6 tablespoons * 15 milliliters/tablespoon = 90 milliliters

I can use proportions and conversions factors to convert measurements between different units.
