3 1/9 as a Decimal

Professor Greenline Explaining Math Concepts
Foundation

Advance Topics

It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part of the whole. It has two parts: numerator (the number on the top) here, 1 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 9. A decimal is a way to represent a number that is not whole, using a decimal point (.) to separate the whole part from the fraction part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.

What is 3 1/9 as a decimal?

3 1/9 as a decimal

 

Answer

 

3 1/9 in decimals can be written as 3.11111….. It is a recurring decimal, indicating it repeats the same digit infinitely.

 

Explanation

 

To convert 3 1/9 into a decimal, we first convert the fraction 1/9. Let's see the step-by-step breakdown of this process:

 

Step 1: Identify the whole number (3) and the fraction (1/9).

 

Step 2: Convert the fraction 1/9 into a decimal.

 

Step 3: Use division to convert 1/9. Here, 1 is smaller than 9, so we use the decimal method, giving us 0.1111.

 

Step 4: Divide 1 by 9. Since 1 is less than 9, we add a decimal point and a zero, making it 10.

 

Step 5: Divide 10 by 9 to get 1, with a remainder of 1.

 

Step 6: Bring down another 0, making it 10 again, and repeat the division. This process continues indefinitely, resulting in a recurring decimal.

 

Finally, add the whole number 3 to the decimal part to get 3.1111…..
