To write an odd five-digit number using the digits 4, 5, 6, 7, and 8 once each, we need to make sure that the units digit (the rightmost digit) is odd.

1. Let's consider the units digit first. The odd digits among the given digits are 5, 7, and so we can choose the units digit from these numbers. Let's choose 7 as the units digit.

2. Next, we need to determine the placement of the other digits. Since we want the number to be odd, we can place the remaining digits in any order as long as the leftmost digit is not zero.

3. For the remaining digits, we can arrange them in any order. Let's choose the remaining digits as 8, 6, 5, and 4.

4. Now, we can arrange these remaining digits to form a four-digit number. Let's choose 8654.

5. Finally, we can combine the number from step 4 with the units digit from step 1 to form a five-digit number. So, the odd five-digit number is 86547.

In standard form: 86547
In word form: Eighty-six thousand, five hundred forty-seven
