## How-to: What is (43)10 in binary?

The below step-by-step solution shows how to convert (43)10 to its equivalent binary code or number. Arranging or writing the remainders from MSB to LSB of successive MOD-2 operation for decimal 43 forms the binary equivalent of 43.

Solved Example:
What is the binary equivalent of 43?

step 1 Observe the input parameters, values and what to be found:

Input values:
Decimal Number = (41)10

what to be found:
Which binary value is equal to the decimal number 43?
(43)10 = (?)2

step 2 Perform successive MOD-2 operation for decimal 43, and mark the initial remainder as LSB and the final remainder as MSB as like the below:

Successive MOD-2 Operation for 43:
 43 MOD-2 43 / 2 = 21 Remainder is 1 → LSB 21 MOD-2 21 / 2 = 10 Remainder is 1 10 MOD-2 10 / 2 = 5 Remainder is 0 5 MOD-2 5 / 2 = 2 Remainder is 1 2 MOD-2 2 / 2 = 1 Remainder is 0 1 MOD-2 1 / 2 = 0 Remainder is 1 → MSB

step 3 Write the remainders of MOD-2 operation for 43 from MSB to LSB forms the binary equivalent for 43:
101011
4310 = 1010112

Therefore,
the binary equivalent of 43 is (101011)2
