Whats 15,677 and 30,944 and 87,142 and 62,763 round to the nearest ten thousands

15,677 = 20,000

30,944 = 30,000

87,142 = 90,000

62,763 = 62,000

Ten thousands means 10,000

But if it is something like 10,000 - 14,000 you round down

If it is 15,000 - 20,000 you round up

so 1-4 round down 5-10 round up
