# 55 in Binary

Decimal 55 in binary conversion provides the detailed information on what is the binary equivalent of (55)10, and the step-by-step work for how to convert the decimal (base-10) number 55 to its binary (base-2) equivalent.

(55)10 in binary is equal to:
(55)10 = (?)2
Perform successive MOD-2 operation for decimal 55, and mark the initial remainder as LSB and the final remainder as MSB as like the below.

 55 MOD-2 55 / 2 = 27 Remainder is 1 → LSB 27 MOD-2 27 / 2 = 13 Remainder is 1 13 MOD-2 13 / 2 = 6 Remainder is 1 6 MOD-2 6 / 2 = 3 Remainder is 0 3 MOD-2 3 / 2 = 1 Remainder is 1 1 MOD-2 1 / 2 = 0 Remainder is 1 → MSB
Arrange the remainders from MSB to LSB forms the binary equivalent of 55.
5510 = 1101112

Hence,
55 in binary is 110111

where,
5510 is the given decimal number,
10 in 5510 represents the base-10 or decimal number system,
1101112 is the binary equivalent of the decimal 41,
2 in 1101112 represents the base-2 or binary number system.
