Round 1,585 to the
nearest ten. Let me rewrite the number. 1,585 to the nearest ten. So we want to focus
on the tens place. If we were to round it up, we
would go to 1,500-- let me color code it. We would round up to 1,590. The 8 would round up to a 9. And 90, if we were to round
down, we would go to 1,500, and we would round down to 80. So these are our two choices. Now we've seen the last
two examples. If the place to the right
of it is 5 or greater, we round up. Well, the place to the
right of it is definitely 5 or greater. It is 5, so we round up. So it is 1,590. And we're done!
