Question

What is 321 octal in binary?

Answer 1

To convert **321** from octal to binary, follow these steps:

### Step 1: Convert each octal digit to its 3-bit binary equivalent.
Octal is a base-8 system, and each octal digit corresponds to exactly three binary digits (since \(8 = 2^3\)).

Let's break down **321** (octal):

- 3 in octal = 011 in binary
- 2 in octal = 010 in binary
- 1 in octal = 001 in binary

### Step 2: Combine the binary equivalents.
Now, just put all the binary digits together:

**321 (octal) = 011 010 001 (binary)**

So, **321 octal = 110100001 binary**.
