Converting from Base 10 to Base 9: A Comprehensive Guide

Understanding how to convert numbers between different bases is a fundamental concept in computer science and mathematics. This article focuses on the conversion of numbers from base 10, the decimal system we use every day, to base 9, a system that utilizes nine unique digits.

In our familiar base-10 system, we have ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) to represent all numbers. Each position in a base-10 number signifies a power of 10. For example, the number 532 can be expressed as (5 10^2) + (3 10^1) + (2 * 10^0).

Similarly, base 9 uses nine digits (0, 1, 2, 3, 4, 5, 6, 7, 8) and each position in a base-9 number represents a power of 9.

Converting from Base 10 to Base 9: Step-by-Step

Let’s break down the process of converting a base-10 number to its base-9 equivalent using the example of the decimal number 123:

  1. Divide the decimal number by the new base: Divide 123 by 9, which gives us 13 with a remainder of 6.

  2. Note the remainder: The remainder, 6, becomes the rightmost digit of our base-9 number.

  3. Repeat the process with the quotient: Divide the quotient from the previous step, 13, by 9. This results in 1 with a remainder of 4. The remainder, 4, becomes the next digit to the left in our base-9 number.

  4. Continue until the quotient is zero: Divide the new quotient, 1, by 9. This gives us 0 with a remainder of 1. The remainder, 1, becomes the leftmost digit.

  5. Combine the remainders: Combining the remainders from each step gives us 146.

Therefore, the base-10 number 123 is equivalent to 146 in base 9 (146_9).
