b. 73 782 489, 73 782 498, 73 782 849, 73 782 894

c. 83 242 283, 83 243 228, 83 243 282, 83 243 822

d. 44 219 248, 44 219 284, 44 219 824, 44 219 842

e. 63 318 278, 63 318 287, 63 318 827, 63 318 872

f. 63 318 278, 63 318 287, 63 318 827, 63 318 872

Answer :

To arrange the given numbers in ascending order, we need to compare each number from left to right, beginning with the largest place value (leftmost digit). We then proceed digit by digit until we can determine their order.

Let's go through each set one at a time:

a.

  1. 22,256,267
  2. 22,256,276
  3. 22,256,627
  4. 22,256,672

Here, we compare each number and rearrange them starting from the smallest:

22,256,267 < 22,256,276 < 22,256,627 < 22,256,672

b.

  1. 73,782,489
  2. 73,782,498
  3. 73,782,849
  4. 73,782,894

The numbers in ascending order are:

73,782,489 < 73,782,498 < 73,782,849 < 73,782,894

c.

  1. 83,242,283
  2. 83,243,228
  3. 83,243,282
  4. 83,243,822

Arranged in ascending order:

83,242,283 < 83,243,228 < 83,243,282 < 83,243,822

d.

  1. 44,219,248
  2. 44,219,284
  3. 44,219,824
  4. 44,219,842

In ascending order, these numbers are:

44,219,248 < 44,219,284 < 44,219,824 < 44,219,842

e.

  1. 63,318,278
  2. 63,318,287
  3. 63,318,827
  4. 63,318,872

The order from smallest to largest is:

63,318,278 < 63,318,287 < 63,318,827 < 63,318,872

f.

  1. 63,318,278
  2. 63,318,287
  3. 63,318,827
  4. 63,318,872

Just like in the previous set, the order is:

63,318,278 < 63,318,287 < 63,318,827 < 63,318,872

By comparing numbers digit by digit, we ensure that they are ordered correctly from the smallest to the largest number.
