A bottle of orange juice holds 1.89 liters of juice How many milliliters of juice are in the bottle?

You didn't say that the bottle is completely full of juice, but I will assume that it is. Otherwise it will be impossible to answer. One liter contains 1000 milliliters. You multiply the liters by 1000, which means move the decimal point three places to the right. So 1.89 liters = 1890 milliliters.
