Answer

13
Answer for screen readers

So, the decimal equivalent of the binary number 1101 is 13.

Steps to Solve

  1. Identify the binary number

Carefully note down the given binary number. For example, let's take the binary number 1101.

  1. Assign place values to each binary digit

Each binary digit (bit) has a place value that is a power of 2, starting from the rightmost bit (which has a place value of $2^0$). For the binary number 1101, the place values are:

[ 1 \times 2^3, 1 \times 2^2, 0 \times 2^1, 1 \times 2^0 ]

  1. Calculate each term's value

Multiply each binary digit by its corresponding place value:

[ 1 \times 2^3 = 8 ] [ 1 \times 2^2 = 4 ] [ 0 \times 2^1 = 0 ] [ 1 \times 2^0 = 1 ]

  1. Sum all the terms

Add the results from the previous step to get the decimal value:

[ 8 + 4 + 0 + 1 = 13 ]

So, the decimal equivalent of the binary number 1101 is 13.

So, the decimal equivalent of the binary number 1101 is 13.

More Information

Binary to decimal conversion is a fundamental concept in computer science and digital electronics.

Tips

Common mistakes include incorrectly assigning place values or forgetting to multiply the binary digit by its corresponding power of 2.
