Question

In 2007, Pennsylvania had approximately121,580miles of public roads, what is 121,580 rounded to the nearest thousand?

Answer 1

121,580 rounded to the thousands is 122,000

Answer 2

Answer:

122,000 miles.

Explanation:

If we want to round up the number 121,580 to the nearest thousand, then we must take the first three digits from the cipher (5, 8 , and 0), as these are the digits that come before the thousands (the fourth digit).

Take the digits mentioned before and combine them into a single number (580). Now analyze the quantities required to make this number a 0 and a 1000.

580 - 0 = 580.          (Making it 0).

1000 - 580 = 420.    (Making it 1000).

The right way to round up 580 to the nearest thousand is to take the lowest number of the previous two:

420 < 580               (420 is the lowest number).

Which means that adding 420 to 121,580 is the right way to round it up to the nearest thousand.

121,580 + 420 = 122,000 --> Answer
