85001 rounded to the nearest ten thousand is 90,000. Because there is a 5 in the thousands place, the 8 in the ten thousands place rounds up to 9. Always use the numeral to the right of the place value you are rounding. If it is 5 or greater the number increases. If it is less than 5, it remains the same.
First ask yourself what is the ten thousands ? If its 8 then your right . now ask what is on the left of 8 ? On the left of 8 is 5 . If the number 1-4 are on the left then dont change the ten thousands but if it is 5-6 then add +1 to the number to be rounded off . So now the answer is 95001 . But what you are going To do next is your going to make all the numbers on the left of 8 be 0 . But dont mind then numbers on the right of the number to be rounded off . Therefore the answer is 90000.
