The binary number 10110 represents (1 x 16) + (0 x 8) + (1 x 4) + (1 x 2) + (0 x 1) and 16 + 4 + 2 = 22.
An ancient method of converting decimal numbers to binary form is to halve the number until 1 is reached. When halving an odd number round down to the number below (13 halved = 61/2 round down to 6). If the number is even then record a 0, if the number is odd then record a 1. 22 ................is even .......0 22 ÷ 2 = 11..is odd..........1 11 ÷ 2 = 5....is odd..........1 5 ÷ 2 = 2......is even........0 2 ÷ 2 = 1......is odd..........1 The binary equivalent of 22 is therefore 10110
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.
22 + 21 + 20 + 0 + 2-2 equals 7.25
In binary this would be written as 1011. This is because in binary (from right to left) the digits in this number mean: (1 * 20) + (1 * 21) + (0 * 22) + (1 * 23). This, of course, is equal to (1 * 1) + (1 * 2) + (0 * 4) + (1 * 8), which equals 1 + 2 + 0 + 8, which equals 11 (in decimal).

The binary number 10110 represents (1 x 16) + (0 x 8) + (1 x 4) + (1 x 2) + (0 x 1) and 16 + 4 + 2 = 22.

To convert from decimal to binary, keep dividing by two, recording the remainder from right to left (% is the symbol for the remainder after dividing): 22 % 2 = 0 ... "0" 11 % 2 = 1 ... "10" 5 % 2 = 1 ... "110" 2 % 2 = 0 ... "0110" 1 % 2 = 1 ... "10110" So 22 in base 10 is 10110 in base 2 (binary).
value of the position: | 16 | 8 | 4 | 2 | 1 | your number | 1 | 0 | 1 | 1 | 0 | sum the value of the position for each position where you have a 1 so 16 + 4 + 2 = 22

22 + 21 + 20 + 0 + 2-2 equals 7.25
1102 = 1*22 + 1*21 + 0*20 = 4 + 2 + 0 = 6
111101 to decimal = 25 + 24 + 23 + 22 + 01 + 20 = 32 + 16 + 8 + 4 + 0 + 1 = 61
