You may want to write the decimal equivalent for each position as we did in the following example.
Add only the values indicated by a 1.
You should make sure that the decimal values for each position are properly aligned before adding.
For practice let’s convert these binary numbers to decimal:
Q91.
100102
Q92.
11111002
Q93.
10101012
Q94.
0.01012
Q95.
0.10102
Q96.
1101101.11112
Octal to Decimal
Conversion of octal numbers to decimal is best done by the positional notation method. This process
is the one we used to convert binary numbers to decimal.
First, determine the decimal equivalent for each position by multiplying 8 by itself the number of
times indicated by the exponent. Set up a bar graph of the positions and values as shown below:
