7 = 111.
5 = 101.
So simple 5*7 = 35.
Now it will be convert in binary
32 16 8 4 2 1
1 0 0 0 1 1
35=100011.
The same technique will be used if large no occur.

111 in decimal is 7 and 101 in decimal is 5.
now multiply 7 and 5 ie. 7*5=35.
Next, convert 35 into binary by using 32-bit representation.
32 16 8 4 2 1.
1 0 0 0 0 1 (32+2+1=35 so put 1 in place of 32,2,1 and 0 in remaining places).

111->7
101->5
7*5=35
35/2=17 --------------> 35%2=1
17/2=8 --------------> 17%2=1
8/2=4 --------------> 8%2=0
4/2=2 --------------> 4%2=0
2/2=1 --------------> 2%2=0
--------------> 1%2=1
Reading in reverse order we get the answer 100011.
101->5
7*5=35
35/2=17 --------------> 35%2=1
17/2=8 --------------> 17%2=1
8/2=4 --------------> 8%2=0
4/2=2 --------------> 4%2=0
2/2=1 --------------> 2%2=0
--------------> 1%2=1
Reading in reverse order we get the answer 100011.

How to change 35 into binary no 100011? Please explain.

@ Tauqeer.
100011= 1*2^5+0*2^4 + 0*2^3+0*2^2 + 1*2^1+1*2^0.
= 32+0+0+0+2+1 = 35.
100011= 1*2^5+0*2^4 + 0*2^3+0*2^2 + 1*2^1+1*2^0.
= 32+0+0+0+2+1 = 35.

In binary 1 is written as 001 and 2 is 010, three is 011, 4 is 100, 5 is 101, 6 is 110 and seven is 111 eight is 1000 nine is 1001 and ten is 1010 accordingly 20 is 10100 and 30 is 11110 plus five 101 total would be 10001.
The concept is 1+1=0 and carry forward 1, further if we multiply 7*5=35 it written in binary as 100011 is.
