Forming 3-Digit Odd-Digit Numbers: An SEO-Optimized Guide
How Many 3-Digit Numbers Can Be Formed Using Only Odd Digits?
To determine how many 3-digit numbers can be formed using only odd digits, we first identify the odd digits available. The odd digits are: 1, 3, 5, 7, and 9. This gives us a total of 5 odd digits.
Understanding the Problem
For a 3-digit number, each digit can be filled independently:
Hundreds Place
Since we are forming a 3-digit number, the hundreds place can be filled with any of the 5 odd digits: 1, 3, 5, 7, 9.
Tens Place
The tens place can also be filled with any of the 5 odd digits.
Units Place
Similarly, the units place can be filled with any of the 5 odd digits.
Since each of the three places can be filled in 5 ways, the total number of 3-digit numbers formed is calculated as follows:
Total numbers 5 × 5 × 5 53 125
Thus, the total number of 3-digit numbers that can be formed using only odd digits is 125.
