Important Notes: (20)8 in Decimal
The below are some of the important notes to be remembered while converting the (base-8) octal number 20 into a (base-10) decimal equivalent.
The below step-by-step solution shows how to convert (20)8 into decimal equivalent. To find the decimal equivalent of (20)8, multiply 80 with the right most digit, 81 with the left subsequent digit and so on until the left most digit of the given octal number 20. The sum of all individual products is the decimal equivalent of octal 20.
Solved Example:
Convert (20)8 into decimal equivalent.
step 1 Observe the input parameters, values and what to be found.
Input values:
Octal Number = 208
What to be found:
What is the decimal equivalent of (20)8?
step 2 Multiply 80 with the right most digit, 81 with the left subsequent digit and so on until the left most digit of the given octal number 20. Therefore, arrange the given decimal number 20 in the expression form as like the below:
= (2 x 81) + (0 x 80)
step 3 Resolve the powers of 8 in the above equation:
= (2 x 8) + (0 x 1)
step 3 Simplify the above equation further:
= 16 + 0
= 16
(20)2 = (16)10
Therefore,
16 is the decimal equivalent of octal number (20)8
