It is 2380.
Most schools wrongly teach you to always round a half up (so the answer would be 2390) but, while this is a simple rule to teach, it is not really correct. Under this rule:
60
36,184 rounded to the nearest ten thousands place is 40,000.
2602 rounded to the nearest ten is 2600.
20
Rounded to the nearest ten it is: 564,630
2400
60
It is then 740 when rounded to the nearest ten.
To round 31 to the nearest ten, we look at the digit in the tens place, which is 3. Since 3 is closer to 0 than to 10, we round down to the nearest ten. Therefore, 31 rounded to the nearest ten is 30.
36,184 rounded to the nearest ten thousands place is 40,000.
2602 rounded to the nearest ten is 2600.
