📝Explanation to Question 1️⃣ 8️⃣👆👆👆
Question: The binary expression of the decimal number 31 is:___

✅Solution 

To convert a decimal number to its binary equivalent, we can use the following steps:

1. Divide the decimal number by 2.
2. Write down the remainder (0 or 1).
3. Divide the quotient by 2.
4. Write down the remainder.
5. Repeat steps 3 and 4 until the quotient is 0.

✅Let's apply these steps to convert the decimal number 31 to binary:

Step1 31 ÷ 2 = 15 remainder 1
Step2. 15 ÷ 2 = 7 remainder 1
Step3. 7 ÷ 2 = 3 remainder 1
Step4. 3 ÷ 2 = 1 remainder 1
Step5. 1 ÷ 2 = 0 remainder 1

Reading the remainders from bottom to top, we get the binary expression of 31 as:

31 = (1 1 1 1 1)_2

Therefore, the binary expression of the decimal number 31 is 11111❤️
