to translate a number to binary, you need to break it down to a sum of 2^n s.
5 = 4 + 1 = 1 * 2^2 + 0*2^1 + 1 * 2^0 =>
101 represent 5 in binary.
10 = 8 + 2 = 1 * 2^3 + 0 *2^2 + 1*2^1 + 0*2^0
so 1010 represent ten.
This is the best I can do to explain it. If it is still confusing, I suggest you spend some time with a math book or sit down with someone to go over it. Although I doubt very much we need to know this in actual programming, you do need to understand it for the test.
good luck

Follow this logic. I came across this some where on the net . It is very simple !!
Start with the decimal and then go on dividing by 2 and recording the remainder. The first remainder becomes LSD but is written from MSD - LSD after convertion is complete
Following example should make clear what I mean.
Let us start with your number i.e 6
6/2 = 3 Remainder is 0 - LSD
3/2 = 1 Remainder is 1
1/2 = 0 Remainder is 1 - MSD
You can put any number of 0 for Most Significant Bits hence the
value becomes is 0110 (written from MSD to LSD)
Did it help you ?
