The tenth place will be the number right after the decimal "." You have to look at the number behind the 7 to see if the 7 will stay at 7 or if it will round up to 8. Since 5 means you round up, you round the 7 to an 8, giving you:
3.8
For 36 3 6 13. For 48 4 8 24. I think there are more but I can't think of them
You can predict that it's odd because the end of the 2 numbers is 1 and 1 x 1 is 1 and one is an odd number. (answer is odd)
The nine rounds up so it would be 400,000
