Which is the best estimate of the product 17 divided by 33 times 11 divided by 20

17/33x11/20=___
So just do the problem in order. Then you get an answer of 0.2833.
Then to check your answer do the estimate thing. So 17 rounds to 20 and 33 rounds to 30 and 11 rounds to 10 and I like 20 so I'll stick with that.
20/30x10/20=___
And when you put the answer in a calculator you get .33333whatever so that equals 1/3. So You know that 1/3 is the right answer cause it is close to the exact one.

The answer is 225 miles per 4.5 hours. hope this ; )
