To find all possible 3-digit numbers whose digits' sum is 12, we need to consider the different combinations of digits that add up to 12.
Let's break it down step-by-step:
Step 1: List all possible digit combinations
Start with the largest digit (9) since we are looking for 3-digit numbers.
Combination 1: 9 + 1 + 2 = 12
Combination 2: 9 + 2 + 1 = 12
Combination 3: 8 + 2 + 2 = 12
Combination 4: 8 + 3 + 1 = 12
Combination 5: 8 + 1 + 3 = 12
Combination 6: 7 + 3 + 2 = 12
Combination 7: 7 + 2 + 3 = 12
Combination 8: 7 + 4 + 1 = 12
Combination 9: 7 + 1 + 4 = 12
Combination 10: 6 + 4 + 2 = 12
Combination 11: 6 + 2 + 4 = 12
Combination 12: 6 + 3 + 3 = 12
Combination 13: 6 + 3 + 3 = 12
Combination 14: 5 + 4 + 3 = 12
Combination 15: 5 + 3 + 4 = 12
Combination 16: 5 + 5 + 2 = 12
Combination 17: 5 + 2 + 5 = 12
Combination 18: 4 + 4 + 4 = 12
Combination 19: 4 + 4 + 4 = 12
Combination 20: 4 + 5 + 3 = 12
Combination 21: 4 + 3 + 5 = 12
Combination 22: 4 + 3 + 5 = 12
Combination 23: 3 + 3 + 6 = 12
Combination 24: 3 + 3 + 6 = 12
Combination 25: 3 + 4 + 5 = 12
Combination 26: 3 + 5 + 4 = 12
Combination 27: 2 + 5 + 5 = 12
Combination 28: 2 + 5 + 5 = 12
Combination 29: 1 + 5 + 6 = 12
Combination 30: 1 + 6 + 5 = 12
Step 2: Form three-digit numbers
Now, we will form three-digit numbers using these digit combinations.
Resulting 3-digit numbers:
112, 121, 222, 813, 831, 732, 723, 741,
714, 642, 624, 633, 633, 543, 534, 552,
525, 444, 444, 453, 435, 435, 336, 336,
345, 354, 255, 255, 156, 165
So, these are all the possible 3-digit numbers whose digits sum up to 12.
To find all possible three-digit numbers whose sum of digits is 12, we can use a systematic approach.
We start by listing the possible combinations of digits whose sum is 12. These combinations can be obtained by adding different digits together. For example:
1 + 1 + 10 = 12
1 + 2 + 9 = 12
1 + 3 + 8 = 12
1 + 4 + 7 = 12
1 + 5 + 6 = 12
2 + 2 + 8 = 12
2 + 3 + 7 = 12
2 + 4 + 6 = 12
3 + 3 + 6 = 12
3 + 4 + 5 = 12
4 + 4 + 4 = 12
Now, we can use these combinations to find the possible three-digit numbers. To do this, we put the largest digit as the hundred's digit, the second-largest digit as the ten's digit, and the smallest digit as the unit's digit. This will give us all possible three-digit numbers that meet the criteria.
Using the combinations above, we can generate the following three-digit numbers:
112
129
138
147
156
228
237
246
336
345
444
Therefore, these are all the possible three-digit numbers whose sum of digits is 12.
