Question

Ratika,s computer teacher has asked her to convert an octal number to decimal number. Suggest her the method which she should apply in converting the octal number.

Answer 1

Answer:

Octal Example: 547

Start with

x=0

add the first digit - x=5

Now since there are more digits to follow multiply by 8 (because it's an octal number) - x=40

add the next digit  - x=(40+4)=44

Now since there are more digits to follow multiply by 8 - x=352

add the next digit x=352+7=359

Now since there are no more digits we are done.

Hope this helps! :)
