CONVERTING BINARY TO DENARY


The small number above the binary number is its weighting (how much it is worth).

A 1 in the left hand column is worth 16 denary.

The 1 next to it is worth 8.
 
 


 
 
Add all the weightings with a 1 in them.

The result is the denary number.


 


The answer is 25.
