Question

This number was rounded to the nearest hundred thousand. List the possible digits that could go in the ten thousands place to make this statement true. 1_9,644 = 100,000.

Answer 1

The list of possible digits are 0, 1, 2, 3, or 4.

Explanation:

Consider the provided number.

1_9,644 = 100,000

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, then no need to change the rounding digit.

If 5, 6, 7, 8, or 9 follow the number, then rounding digit rounds up by one number.

Since hundred thousand digit is same i.e 1. so the number on the ten thousands place should be 0, 1, 2, 3, or 4.

If we place any of the above number on the blank space, the round off of the number will be 100,000.

Thus, the list of possible digits are 0, 1, 2, 3, or 4.
