Which process converts a binary number to decimal using positional notation?

• A. Use positional notation
• B. Convert Binary to Decimal
• C. Binary Number System
• D. Decimal Number System

Answer: (B)

Positional notation is about using the base and the position of each digit to determine its value. Converting a binary number to decimal uses that idea with base 2: multiply each binary digit by 2 raised to the power of its position (counting from zero on the right) and sum these products. This explicit process is describing converting binary to decimal, which is why it’s the best choice. The other options point to the general idea of positional notation or to the number systems themselves rather than the conversion action. For example, binary 1011 becomes 1×2^3 + 0×2^2 + 1×2^1 + 1×2^0 = 8 + 0 + 2 + 1 = 11 in decimal.
