Each week, a family consumes six 693-milliliter bottles of orange juice. Determine, in liters, the amount of orange juice in each bottle.
Here, we’re told that this family has six 693-milliliter bottles of orange juice each week. It might be very tempting, particularly in an exam, to jump straight in and multiply six by 693. But what we’re really being asked here is the quantity of orange juice in each bottle in terms of liters. So we’ll not be doing any multiplying. We’ll just be converting between milliliters and liters.
To do this, we’ll need to recall a key conversion fact. And that is that there are 1000 milliliters in one liter. This means that if we’re changing a quantity in milliliters into liters, we need to divide by 1000. We can then take our value of 693 milliliters and divide by 1000. We can remember that when we’re dividing by 1000, our digits move three places to the right.
This will give us a value of 0.693, and that’s our answer. If there is 693 milliliters of orange juice in each bottle, then that’s equal to 0.693 liters.
