One very simple form of estimation is rounding. Rounding is often the key skill you need to quickly estimate a number. This is where you make a long number simpler by ‘rounding’, or expressing in terms of the nearest unit, ten, hundred, tenth, or a certain number of decimal places.

the answer is:                                                                                                                                                                                                 when we count 1 to 10  5 was the middle. So , if i ask nearest to the 46 then it was 50 because 6 was more than 5. If i ask nearest to 42 then it was 40 because 2 is less than 5. so the answer is 600 multiply 90 = 54000

563 x 87 
563 can be rounded off to the nearest hundred, so it will change to 600.
87 can be rounded off to the nearest tens, so it will change to 90.
Now multiply both the numbers. That is, 600 x 90.
Hence, the answer will be 54000.

563x87:-
1. First, we have to estimate 563 into the nearest hundreds so it will be 560.
2. Then, we have to estimate 87 into the nearest tens so it will be 90.
3. Then we have to multiply both of them
                                              
                                         600                 
                                         x90
                                    -------------

                                     54000
                                   -------------

4. So, the answer is 54,000

Hope that helps

5400 IS THE ANSWER

1) First, estimate one number to its greatest place.
2) Now, estimate the other number to its greatest place.
3) The last step is to, multiply both the estimated number.

Here's an example:
Q. Find the estimated product of 225 X 60
225 = 200
60 = 60
200 x 60 = 12000
Therefore, the estimated product of 225 x 60 is 12, 000.
Now, I hope you understood it and try solving the sum your working on.
Hope it was helpful!

when we count 1 to 10? 5 was the middle. So , if i ask nearest to the 46 then it was 50 because 6 was more than 5. If i ask nearest to 42 then it was 40 because 2 is less than 5. so the answer is 600 multiply 90 = 54000

563 x 87
563 can be rounded off to the nearest hundred, so it will change to 600.
87 can be rounded off to the nearest tens, so it will change to 90.
now multiply both the numbers. that is, 600 x 90.
hence, the answer will be 54000.
