Yesterday, Ms. Hoffman asked for your help. She thought maybe she could use estimation to make converting from Turkish Lira to US Dollars easier.
Did you think of a good way?
Here is one way:
Ms. Hoffman knows that 0.45 is close to 0.50. (Just like 45 is close to 50 when you round to the nearest 10)
$0.50 is half of $1.00.
If 1 Turkish Lira is about half of $1.00 then about 2 Turkish Lira equal $1.00. Make sense?
Now it is easy! All you have to do is divide how many Turkish Lira you have by 2 to get the number of US dollars.
Let's try a problem now!
10 divided by 2 = 5! The towel is about 5 dollars. Remember, it is not EXACTLY 5 dollars, because we are estimating, but it is close!

Ms. Hoffman bought a special Turkish towel. It cost 10 TL. How many dollars was it?
10 divided by 2 = 5! The towel is about 5 dollars. Remember, it is not EXACTLY 5 dollars, because we are estimating, but it is close!
