Round 9,614,018,007 to the nearest ten million.

  1. We are rounding to the nearest ten million.
    9,614,018,007, with the first 1 labeled, ten millions position.
  2. Observe the digit immediately to the right of the ten millions position. It is 4. Since 4 is less than 5, we round down by replacing 4 and all the digits to its right with zeros.
    9,610,000,000

Thus, 9,614,018,007 rounded to the nearest ten million is 9,610,000,000.

Round 148,422 to the nearest million.

  1. Since we are rounding to the nearest million, we'll have to imagine a digit in the millions position. We'll write 148,422 as 0,148,422.
    0,148,422, with the 0 labeled, millions position.
  2. The digit immediately to the right is 1. Since 1 is less than 5, we'll round down by replacing it and all the digits to its right with zeros.
    0,000,000
    This number is 0.

Thus, 148,422 rounded to the nearest million is 0.

Round 397,000 to the nearest ten thousand.

  1. We are rounding to the nearest ten thousand.
    397,000, with the 9 labeled, ten thousand position.
  2. The digit immediately to the right of the ten thousand position is 7. Since 7 is greater than 5, we round up by replacing 7 and all the digits to its right with zeros and adding 1 to the digit in the ten thousands position. But 9 + 1 = 10 and we must carry the 1 to the next (the hundred thousands) position.
    400,000

Thus, 397,000 rounded to the nearest ten thousand is 400,000.
