Decimal to Binary

Have you ever wondered how computers understand numbers? They use a special number system called binary. Let's learn how to convert decimal numbers to binary. This guide is simple and perfect for kids!

What is a Decimal Number?

We use decimal numbers every day. They are the numbers from 0 to 9. This system is also known as base-10.

What is a Binary Number?

Binary numbers are different. They only use 0 and 1. This system is also known as base-2.

Why Do We Convert Decimal to Binary?

Computers use binary numbers. To understand decimal numbers, computers convert them to binary. This helps computers process information quickly.

Steps to Convert Decimal to Binary

We can convert decimal numbers to binary in a few simple steps. Let's learn how!

Step 1: Divide The Decimal Number By 2

Start by dividing the decimal number by 2. Write down the quotient and the remainder. The remainder will be either 0 or 1.

Step 2: Repeat The Process

Take the quotient from the previous step. Divide it by 2 again. Write down the new quotient and remainder.

Step 3: Continue Until The Quotient Is 0

Keep dividing by 2 until the quotient is 0. Write down all the remainders.

Step 4: Write The Binary Number

Read the remainders from bottom to top. This gives you the binary number.

Example: Convert 10 to Binary

Let's convert the decimal number 10 to binary. Follow the steps below:

• Divide 10 by 2: Quotient = 5, Remainder = 0
• Divide 5 by 2: Quotient = 2, Remainder = 1
• Divide 2 by 2: Quotient = 1, Remainder = 0
• Divide 1 by 2: Quotient = 0, Remainder = 1

Read the remainders from bottom to top: 1010. So, 10 in decimal is 1010 in binary.
