To convert decimal to binary, divide the decimal number you want to convert by 2 and write down the remainder. Repeat this until the final result is zero. The remainders you wrote down, written from the last one you wrote to the first (so the opposite order from which you derived them) is the binary equivalent.
So using this method with the number 23 we get:
23/2 = 11 remainder 1
11/2 = 5 remainder 1
5/2 = 2 remainder 1
2/2 = 1 remainder 0
1/2 = 0 remainder 1
So the binary equivalent is 10111

What is the decimal number 23 as a binary number?
The number 23 is 10111 in binary. The digits in a binary number are exponents of 2 rather than 10, so that for a five digit number in binary, the digit places represent 16, 8, 4, 2, 1 instead of increasing values of 10. 10111 = 16+0+4+2+1 = 23
What is the number 27 as a binary number?
The decimal number "27" is written in binary as 11011.This is because binary has a base of 2. This means that the digits are representing multiples of powers of 2 (as opposed to 10 in decimal). This number in binary means (1 * 20) + (1 * 21) + (0 * 22) + (1 * 23) + (1 * 24). In decimal this equals 1 + 2 + 0 + 8 + 16. This, of course, equals 27.
What is the binary number 1111001 is equal to which decimal number?
26 + 25 + 24 + 23 + 20 = 64 + 32 + 16 + 8 + 1 = 121
