It would be 10100.
2010 = 101002
The octal equivalent of decimal number 16 is 20. In octal, each digit represents three binary digits, so converting decimal 16 (which is 10000 in binary) into octal gives 20.
Decimal 20 is 10100 in binary
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.
In binary this would be written as 1010. This is because in binary (from right to left) the digits in this number mean:(0 * 20) + (1 * 21) + (0 * 22) + (1 * 23).This is equal to (0 * 1) + (1 * 2) + (0 * 4) + (1 * 8), which equals 0 + 2 + 0 + 8, which equals 11 (in decimal).

The number 20 in binary is 10100
22 + 21 + 20 + 0 + 2-2 equals 7.25
1102 = 1*22 + 1*21 + 0*20 = 4 + 2 + 0 = 6
26 + 25 + 24 + 23 + 20 = 64 + 32 + 16 + 8 + 1 = 121
111101 to decimal = 25 + 24 + 23 + 22 + 01 + 20 = 32 + 16 + 8 + 4 + 0 + 1 = 61
