When rounding to the nearest hundred thousand, the key is to look at the ten-thousands digit (the fifth digit from the right). The rule for rounding is as follows:
- If the ten-thousands digit is 5 or greater, round up to the next hundred thousand.
- If the ten-thousands digit is 4 or less, round down to the current hundred thousand.
For 200,000, the range of numbers that will round to it is 150,000 to 249,999.
Let's examine each number:
- 99,985: This rounds down to 0 (not applicable).
- 142,026: This rounds to 100,000 (not applicable).
- 165,400: This rounds to 200,000 (selected).
- 220,754: This rounds to 200,000 (selected).
- 1,995,000: This rounds to 2,000,000 (not applicable).
Thus, the numbers that round to 200,000 when rounded to the nearest hundred thousand are 165,400 and 220,754.
