First of all we know about the Estimation.
What is the Estimation?
To estimate the result of multiplication (product), round the numbers to some close numbers that can easily multiply . One method of estimation is to round all factors to the biggest digit (place value) they have.
General rule for rounding:
1 ) If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
2 ) If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
So the last digit of number is 44 which is less then 50 so the number is down to its 10's.
thats the reason why when we estimate the product of 416x9 =3,744 is 3,600.

Assuming you want the expression to be simplified.
We begin with the following:

Simplify the first part,

. That is 25. Now we have this:
Next, simplify

, which is 1/3, and get this:
The next part is

. Simplify the denominator,

, which is 81. Simplify the numerator, which is 1/125. Then divide 1/125 by 81, which we will keep as a fraction for simplicity's sake, but simplify it to

. Now we have:

Now simplify

, which is 0.2, or 1/5. Now we have:
Finally, simplify

. That is 1/27. We have:

Lastly, multiply them all together! Now we are done, with the product of:

That certainly did take a while to type in all the LaTex, so I really hope that helped!
Note- if anything isn't working with the LaTex, just tell me and I'll fix it! (:
