Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Convert the number $\var{ans1}$ to binary.

Gap 0. Gap 1. Gap 2.

Advice

First list the powers of 2 $2^0=1,2^1=2,2^2=4,2^3=8,2^4=16,2^5=32...$

(a) $\var{ans1}=(\var{b2}\times4)+(\var{b3}\times2)+(\var{b4}\times1)$ ,

So, the answer is $\var{b2}\var{b3}\var{b4}$ .

(b) $\var{ans2}=(\var{b1}\times16)+(\var{b2}\times8)+(\var{b3}\times4)+(\var{b4}\times2)+(\var{b5}\times1)$ ,

So, the answer is $\var{b1}\var{b2}\var{b3}\var{b4}\var{b5}$ .

(c) $\var{ans3}=(\var{b1}\times128)+(\var{b2}\times64)+(\var{b3}\times32)+(\var{b4}\times16)+(\var{b5}\times8)+(\var{b6}\times4)+(\var{b7}\times2)+(\var{b8}\times1)$

So, the answer is $\var{b1}\var{b2}\var{b3}\var{b4}\var{b5}\var{b6}\var{b7}\var{b8}$ .
