Answer 2

Underlining the number of decades in each number

To solve this problem, we need to break down each number into decades. A decade is a group of ten ones, or a place value of 10.

For the number 7890: - Thousands place (10^3): 7 - Hundreds place (10^2): 8 - Tens place (10^1): 9 - Ones place (10^0): 0 Underlining the number of decades, which is the sum of the digits in the tens and hundreds place, we get 789_

For the number 1203: - Thousands place (10^3): 0 - Hundreds place (10^2): 1 - Tens place (10^1): 2 - Ones place (10^0): 3 Underlining the number of decades, we get 12_

For the number 25304: - Ten thousands place (10^4): 2 - Thousands place (10^3): 5 - Hundreds place (10^2): 3 - Tens place (10^1): 0 - Ones place (10^0): 4 Underlining the number of decades, we get 533_

For the number 49998: - Ten thousands place (10^4): 4 - Thousands place (10^3): 9 - Hundreds place (10^2): 9 - Tens place (10^1): 9 - Ones place (10^0): 8 Underlining the number of decades, we get 9998_

For the number 183769: - Hundred thousands place (10^5): 1 - Ten thousands place (10^4): 8 - Thousands place (10^3): 3 - Hundreds place (10^2): 7 - Tens place (10^1): 6 - Ones place (10^0): 9 Underlining the number of decades, we get 8376_

For the number 56078: - Ten thousands place (10^4): 5 - Thousands place (10^3): 6 - Hundreds place (10^2): 0 - Tens place (10^1): 7 - Ones place (10^0): 8 Underlining the number of decades, we get 6
