Answer: C) 765
===========================
Step-by-step explanation:
- If we rounded 741 to the nearest tens, then it would round to 740. But we want 770. So we cross this off the list.
- 775 rounds to 780 when rounded to the nearest tens. This is crossed off as well.
- 765 rounds to 770 when rounding to the nearest tens place, it also rounds to 800 when rounded to the nearest hundreds place. Finally, 765 rounds to 1000 when rounded to the thousands place. This shows why 765 is the answer. Other possible answers include {766, 767, 768, 769} if we're only allowed to deal with whole numbers.
- The number 779 rounds to 780 when rounding to the nearest tens place. So we cross this off the list.
