# 43 in Binary

43 in binary is 101011. 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 43 in binary. In this article, let us learn how to convert the decimal number 43 to binary.

## How to Convert 43 in Binary?

**Step 1:** Divide 43 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 |
---|---|

43/2 = 21 | 1 |

21/2 = 10 | 1 |

10/2 = 5 | 0 |

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 43.

Therefore, the binary equivalent of decimal number 43 is 101011.

## FAQs on 43 in Binary

### What is 43 in Binary?

43 in binary is 101011. To find decimal to binary equivalent, divide 43 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.

### How to Convert 43 to Binary Equivalent?

We can divide 43 by 2 and continue the division till we get 0. Note down the remainder in each step.

- 43 mod 2 = 1 - LSB (Least Significant Bit)
- 21 mod 2 = 1
- 10 mod 2 = 0
- 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 43 in binary can be represented as 101011.

### What is the Binary Equivalent of 43 + 76?

43 in binary number system is 101011 and 76 is 1001100. We can add the binary equivalent of 43 and 76 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, (101011)₂ + (1001100)₂ = (1110111)₂ which is nothing but 119.
