The difference between decimal and binary system are-
- The base-10 system, often known as the decimal system, is the oldest and most widely used system of numbers.
- The binary number system, often known as base 2, is used by computers.
<h3>What is decimal system?</h3>
Our daily use of numbers is based on a decimal number system, which uses 10 digits. A number system in mathematics is thought of as the use of digits or symbols to represent numbers.
- The binary number system, the decimal number system, the octal number system, and the hexadecimal number system are the four primary varieties of the number system.
- Given that it was challenging to multiply & divide big numbers by hand in earlier civilizations, this decimal system system is sometimes called as the Hindu-Arabic and Arabic number system.
<h3>What is binary system?</h3>
The base-2 number system is the binary system. That implies that it solely use the digits 0 and 1. The 1 one location is moved to its left into the 2s place when adding one to one, and a 0 is placed in the ones place, yielding the number 10. In such a base-10 system, 10 thus = 10. 10 = 2 in the base-2 system.
- The place values in a base-2 system begin with ones and progress to twos, fours, then eights as one move to its left.
- This is due to the base-2 system's foundation in powers of two.
- A bit is the term for each binary digit.
Therefore, a binary number system only employs two different digits(0 and 1), whereas decimal number system includes ten different digits (ranging from 0 to 9).

Answer:
The angles are <u>155°</u> and <u>25°</u>.
Step-by-step explanation:
Given:
Two supplementary angles are in the ratio of 31:5.
Now, to find the angles.
The sum of two supplementary angles = 180°
Let the ratio of the angles be
.
So, according to question:


<em>Dividing both sides by 36 we get:</em>

So, 
And, 
Therefore, the angles are 155° and 25°.
