Answer 1

1. a. 21470 rounded to the nearest ten is 21470 itself.

b. 12437 rounded to the nearest ten is 12440.

c. 236 rounded to the nearest ten is 240.

2. To estimate the difference between 56735 and 62542 by rounding them to the nearest thousand:

- 56735 rounded to the nearest thousand is 57000.

- 62542 rounded to the nearest thousand is 63000.

The estimated difference is 63000 - 57000 = 6000

3. To estimate the total number of coins to the nearest hundred in both bags:

- The number of points in the blue bag (1841) rounded to the nearest hundred is 1800.

- The number of coins in the green bag (1598) rounded to the nearest hundred is 1600.

The estimated total number of coins is 1800 + 1600 = 3400.
