Convert between different number systems. Fill-in the table below Row 1 only: Decimal Binary Hexadecimal 154

We should know that all decimal numbers use of 10 digits which are (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9)

Similarly binary consists of only two digit (0,1)

Now, 

Step 1 . Divide the whole decimal number by the 2 (binary no.) to get the quotient take  the whole part of the quotient and divide it again by 2 (keep remainder  aside )

Step 2. Keep dividing the quotient until it completely divisible by 2 and  becomes 0.

Step 3. Now write down all the remainders in reverse order to get the converted decimal to binary number.
