Answer:
The answer is: 102 - 45 = 57.
Explanation:
To make this conversion we must use the following formula
If we have a bn-1 binary number .... b1b0 we must multiply each box by its power of 2
Decimal = b0 * 2 b0 + .... bn-1 * 2 bn-1
a.- In this case for binary 1100110
+ 0 * 26 + 1 * 25 + 1 * 24 + 0 * 23 + 0 * 22 + 1 * 21 + 1 * 20 = + 0 * 1 + 1 * 2 + 1 * 4 + 0 * 8 + 0 * 16 + 1 * 32 + 1 * 64
= + 2 + 4 + 32 + 64
= 102
b.- In this case for binary 101101
+ 1 * 25 + 0 * 24 + 1 * 23 + 1 * 22 + 0 * 21 + 1 * 20 = + 1 * 1 + 0 * 2 + 1 * 4 + 1 * 8 + 0 * 16 + 1 * 32
= + 1 + 4 + 8 + 32
= 45
The answer is: 102 - 45 = 57.
