which of the following is rounded to the nearest ten thousands?
A. 30000 b. 23000 c. 27500 d. 27090
To round a number to the nearest ten thousand, you look at the thousands digit. If it is 5 or greater, you round up; if it is less than 5, you round down.
Let's analyze each option:
A. 30000 - This is already at ten thousand, so it remains 30000.
B. 23000 - This is also at ten thousand, so it remains 23000.
C. 27500 - The thousands digit is 7 (which is greater than 5), so you round up to 30000.
D. 27090 - The thousands digit is 7 (which is greater than 5), so you round up to 30000.
The only options that are already rounded to the nearest ten thousand are A (30000) and B (23000).
So, the answer is A. 30000 and **B. 23000
