Question

What is 871 rounded to the nearest ten

Answer 1

871 rounded is; 870.
When you round; you round down if the last digit is under 5. But if it is 5 or above you round up.

This obviously doesn't apply if you are using significant figures.

Hope this helped :)

Answer 2

870 is the answer. when rounding ask yourself whats the number before.
If it's a 1 thru a 4 you round down. If it's 5 trhu 9 you round up.
