Chữ số hàng trăm gấp 3 lần chữ số hàng đơn vị nên chữ số hàng trăm là những chữ số chia hết cho 3.
chữ số hàng trăm là 3, 6, 9.
vậy ta có chữ số hàng đơn vị tương ứng là 1, 2, 3.
vì là số có 3 chữ số chia hết cho 3 nên tổng các chữ số ở hàng trăm, hàng chục, hàng đơn vị là số chia hết cho 3
xét chữ số 3 ở hàng trăm: 321, 351,381
xét chữ số 6 ở hàng trăm: 612, 642, 672
xét chữ số 9 ở hàng trăm: 903, 933, 963, 993
vậy có tất cả 10 số. mik nha!!
Vì là số có 3 chữ số chia hết cho 3 mà chữ số hàng trăm gấp 3 lần chữ số hàng đơn vị nên chữ số hàng trăm phải là những số chia hết cho 3. Suy ra: Chữ số hàng trăm là: 3, 6, 9
Ứng với các chữ số 3, 6, 9 ở hàng trăm, ta được các chữ số hàng đơn vị là: 1, 2, 3
Vì là số chia hết cho 3 nên tổng các chữ số của nó là số chia hết cho 3. Suy ra:
Ứng với các chữ số 3 ở hàng trăm, ta được 3 số là: 321, 351, 381
Ứng với các chữ số 6 ở hàng trăm, ta được 3 số là: 612, 642, 672
Ứng với các chữ số 9 ở hàng trăm, ta được 4 số là: 903, 933, 963, 993
Vậy: Có tất cả 10 số có 3 chữ số chia hết cho 3 mà chữ số hàng trăm gấp 3 lần chữ số hàng đơn vị là các số: 321, 351, 381, 612, 642, 672, 903, 933, 963 và 993
