Question

round the numbers nearest thousands 31275 full of formula

Answer 1

The largest number that is at least 1000 with a "4" in the tens place is 1049, so any number between 1000 and 1049 will round down to 1000. Notice again that we have 50 numbers. So we have 50 + 50= 100 numbers which round to 1000 to the nearest hundreds.

Answer 2

31280 is the answer I think because the number from 1 to 4 will have the answer 31 270 and the number 5to9 as unit digit will have the answer 31 280.
