3 is in the tens spot, so we need to look at the number to the right to see if we round up or down
1 would be rounded down, since it is less than 5, so

Ok so it says round it to the nearest tens. So what you're gonna do is look at the tens place there. So the tens place there is 3. Look at the right of the number 3. So if the number is 1-5,it means that you just need to replace it as 0. And just copy all the leftover numbers on the left. If the number is 6-9,it means that you need to add 1 in the number that is the tens place. And then put a zero at the right of it. And just copy all the leftovers in the right. Hope I helped. Goodluck
