47 in Binary
47 in binary is 101111. 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 6 bits to represent 47 in binary. In this article, let us learn how to convert the decimal number 47 to binary.
How to Convert 47 in Binary?
Step 1: Divide 47 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 |
|---|---|
| 47/2 = 23 | 1 |
| 23/2 = 11 | 1 |
| 11/2 = 5 | 1 |
| 5/2 = 2 | 1 |
| 2/2 = 1 | 0 |
| 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 47.
Therefore, the binary equivalent of decimal number 47 is 101111.

FAQs on 47 in Binary
What is 47 in Binary?
47 in binary is 101111. To find decimal to binary equivalent, divide 47 successively by 2 until the quotient becomes 0. The binary equivalent can be obtained by writing the remainder in each division step from the bottom to the top.
What is the Binary Equivalent of 47 + 74?
47 in binary number system is 101111 and 74 is 1001010. We can add the binary equivalent of 47 and 74 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, (101111)₂ + (1001010)₂ = (1111001)₂ which is nothing but 121.

How to Convert 47 to Binary Equivalent?
We can divide 47 by 2 and continue the division till we get 0. Note down the remainder in each step.
- 47 mod 2 = 1 - LSB (Least Significant Bit)
- 23 mod 2 = 1
- 11 mod 2 = 1
- 5 mod 2 = 1
- 2 mod 2 = 0
- 1 mod 2 = 1 - MSB (Most Significant Bit)
Write the remainders from MSB to LSB. Therefore, the decimal number 47 in binary can be represented as 101111.
Find the Value of 6 × 47 in Binary Form.
We know that 47 in binary is 101111 and 6 is 110. Using the binary multiplication rules (0 × 0 = 0; 0 × 1 = 0 ; 1 × 0 = 0 and 1 × 1 = 1), we can multiply 101111 × 110 = 100011010 which is 282 in the decimal number system. [47 × 6 = 282]
