27, 936
2 (represents for ten thousand)
7 (represents for thousand)
9 (represents for hundreds)
3 (represents for tens)
6 (represents for ones)
..since 27, 936 is rounded to the nearest ten thousand the answer will be 30, 000
..why?
.. kasi yung katabi ng 2 (ten thousand) ay 7 ... since 7 yun, it will be rounded up...
