How do you estimate mixed numbers sums?

In the same way as you estimate them for whole numbers.

Add all the sums, then divide by the number of sums. (ie. the average.)

I think you round it to the nearest whole number...
What number would you use to estimate to sums of 47 and 21?

Which is the only number which is equal to the sum of its digits?
Well, 1 is equal to 1. 9 is equal to 9. So any number from 0 to 9. I do not think this is what is meant by the question. If you mean any number with more than one digit. There is no such number. Because 11 sums to 2. 19 sums to 10. 21 sums to 3. 29 sums to 11. 111 sums 3. 119 sums to 11. The sums do not grow as fast the increase of digits.
