Question

Christine must buy at least 45 fluid ounces of milk at the store. The store only sells milk in 200 milliliter bottles. If there are 33.8 fluid ounces in 1 liter, then what is the smallest number of bottles that Christine could buy? (You may use a calculator on this problem.)

Accepted Answer

First we convert the amount of milk Christine must buy from ounces to liters. We use the conversion factor 1 L33.8 fl.oz to obtain 45 fl.oz 1 L33.8 fl.oz 1.331 L. There are 1000 mL in one liter, and 1331200 6.657, so Christine must buy at least 7 bottles of milk at the store.
