what are the three smallest 7 digit whole numbers that can be made using only the digits 4,3,0,9,2,8,and 5? Each digit must be used exactly one time in each number.

clearly, they will begin with the 3 smallest digits first:

203xxxx
204xxxx
205xxxx

in each case, fill in the x's with the remaining digits, from least to most.

I need help with this one

To find the three smallest 7-digit whole numbers using the digits 4, 3, 0, 9, 2, 8, and 5, we can follow these steps:

Step 1: Arrange the digits in ascending order.

The digits are: 0, 2, 3, 4, 5, 8, and 9.

Step 2: Find the smallest number by combining the digits in the arranged order.

The smallest number is 0234589.

Step 3: Remove the first digit (0) and shift the remaining digits to the left.

The remaining digits are: 2, 3, 4, 5, 8, and 9.

Step 4: Repeat steps 2 and 3 twice more to find the other two smallest numbers.

The second smallest number is 2345890.

The third smallest number is 3458920.

Therefore, the three smallest 7-digit whole numbers that can be made using the digits 4, 3, 0, 9, 2, 8, and 5 are:

1. 0234589
2. 2345890
3. 3458920
