1-55You 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:Q91.10010_{2}Q92.1111100_{2}Q93.1010101_{2}Q94.0.0101_{2}Q95.0.1010_{2}Q96.1101101.1111_{2}Octal to DecimalConversion of octal numbers to decimal is best done by the positional notation method. This processis 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 oftimes indicated by the exponent. Set up a bar graph of the positions and values as shown below:
