Question

Nearest ten thousand and hundred thousand 421,492 895,531

Answer 1

When you are rounding there has to be a 5,6,7,8,9 to make the number go up and a 4,3,2,1 to make the number stay the same. 421,492 to the nearest ten thousand is 420,000 because the 1 indicates that the 2 (in the ten thousands place) stays the same and makes every number behind it a 0. 895,531 to the nearest hundred thousand is 900,000 because the 9 indicates that the 8 (in the hundred thousand place) goes up one number making it 9 and then you make all the numbers behind it a 0.
