AA7A hexadecimal to binary

Here we will show you how to convert the hexadecimal number AA7A to a binary number. First note that the hexadecimal number system has sixteen different digits (0 1 2 3 4 5 6 7 8 9 A B C D E F) and the binary number system has only two different digits (0 and 1).

The four steps used to convert AA7A from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in AA7A by 16⁰, multiply the second to last digit in AA7A by 16¹, multiply the third to last digit in AA7A by 16², multiply the fourth to last digit in AA7A by 16³, and so on, until all the digits are used.

A × 16⁰ = 10
7 × 16¹ = 112
A × 16² = 2560
A × 16³ = 40960

Remember that the hexadecimal number system has sixteen different digits, so when doing the above calculation, we use the following values if applicable: A=10, B=11, C=12, D=13, E=14, and F=15.

Step 2)
Next, we add up all the products we got from Step 1, like this:

10 + 112 + 2560 + 40960 = 43642

Step 3)
Now we divide the sum from Step 2 by 2. Put the remainder aside. Then divide the whole part by 2 again, and put the remainder aside again. Keep doing this until the whole part is 0.

43642 ÷ 2 = 21821 with 0 remainder
21821 ÷ 2 = 10910 with 1 remainder
10910 ÷ 2 = 5455 with 0 remainder
5455 ÷ 2 = 2727 with 1 remainder
2727 ÷ 2 = 1363 with 1 remainder
1363 ÷ 2 = 681 with 1 remainder
681 ÷ 2 = 340 with 1 remainder
340 ÷ 2 = 170 with 0 remainder
170 ÷ 2 = 85 with 0 remainder
85 ÷ 2 = 42 with 1 remainder
42 ÷ 2 = 21 with 0 remainder
21 ÷ 2 = 10 with 1 remainder
10 ÷ 2 = 5 with 0 remainder
5 ÷ 2 = 2 with 1 remainder
2 ÷ 2 = 1 with 0 remainder
1 ÷ 2 = 0 with 1 remainder

Step 4)
In the final step, we take the remainders from Step 3 and put them together in reverse order to get our answer to AA7A hexadecimal to binary:

AA7A hexadecimal = 1010101001111010 binary
