Hex, Binary, and Decimal Drill
Chris Bryant, CCIE #12933
The real key to mastering any conversion involving hex, binary, and decimals is getting plenty of practice before the exam. That way, there's no hesitation on exam day!
Here are a few conversion questions to help you master these skills ...and for more help on becoming a CCNA and CCNP, visit my CCNA Tutorials and 3-Minute Boot Camp pages.
I also have a new (and 100% free!) CCNA OSPF Video Boot Camp on Udemy.com that you really should attend. We'll work together on the trickiest of OSPF configs on live Cisco routers!

And now.. the answers!
1. The hex value A7 indicates 10 units of 16 and 7 units of 1, which gives us a decimal of 167. In turn, that binary string is 10100111.
2. The binary string 00110011 has the 32, 16, 2, and 1 bits set -- add 'em up and you have the decimal 51.
3. The decimal 47 contains 2 units of 16 and 15 units of 1, and in hex that's 2F (F= 15).
4. The hex value 101 represents 1 unit of 256, 0 units of 16, and 1 unit of 1 = the decimal 257.
