400 in Binary

400 in binary is 110010000. Unlike the decimal number system where we use the digits 0 to 9 to represent a number, in a binary system, we use only 2 digits that are 0 and 1 (bits). We have used 9 bits to represent 400 in binary. In this article, let us learn how to convert the decimal number 400 to binary.

How to Convert 400 in Binary?

Step 1: Divide 400 by 2. Use the integer quotient obtained in this step as the dividend for the next step. Repeat the process until the quotient becomes 0.

Dividend Remainder
400/2 = 200 0
200/2 = 100 0
100/2 = 50 0
50/2 = 25 0
25/2 = 12 1
12/2 = 6 0
6/2 = 3 0
3/2 = 1 1
1/2 = 0 1

Step 2: Write the remainder from bottom to top i.e. in the reverse chronological order. This will give the binary equivalent of 400.

Therefore, the binary equivalent of decimal number 400 is 110010000.

How to Convert 400 to Binary Equivalent?

We can divide 400 by 2 and continue the division till we get 0. Note down the remainder in each step.

  • 400 mod 2 = 0 - LSB (Least Significant Bit)
  • 200 mod 2 = 0
  • 100 mod 2 = 0
  • 50 mod 2 = 0
  • 25 mod 2 = 1
  • 12 mod 2 = 0
  • 6 mod 2 = 0
  • 3 mod 2 = 1
  • 1 mod 2 = 1 - MSB (Most Significant Bit)

Write the remainders from MSB to LSB. Therefore, the decimal number 400 in binary can be represented as 110010000.

What is the Binary Equivalent of 400 + 45?

400 in binary number system is 110010000 and 45 is 101101. We can add the binary equivalent of 400 and 45 using binary addition rules [0 + 0 = 0, 0 + 1 = 1, 1 + 1 = 10 note that 1 is a carry over to the next bit]. Therefore, (110010000)₂ + (101101)₂ = (110111101)₂ which is nothing but 445.
