How do you round 390 to the nearest ten?

Answer 1

To round 390 to the nearest ten, you look at the digit in the tens place, which is 9. Since 9 is greater than 5, you round up. Therefore, 390 rounded to the nearest ten is 400.

Answer 2

It is already at the nearest ten'. There are '39' tens.

39 x 10 = 390 .

Answer 3

390 is exactly thirty-nine tens, with nothing left over. So there's no other ten

that's any closer to it than it already is. It's already rounded to tens.
