81/100 as a decimal

Professor Greenline Explaining Math Concepts

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: the numerator (the number on the top) here, 81, represents how many parts out of the whole. The denominator (the number below) shows how many parts make the whole, here it is 100. A decimal is a way to represent numbers that are not whole, using a (.) or a decimal point to separate the whole part from the fraction part. The numbers to the left of the decimal point represent the whole number, and those to the right represent the fractional part.

What is 81/100 as a decimal?

81/100 as a decimalAnswer

 

81/100 in decimals can be written as 0.81. It is a terminating decimal, which means it does not repeat infinitely.

 

Explanation

 

To convert 81/100 into a decimal, we will use division. Here, as 81 is smaller than 100, we will apply the division method, which will give us 0.81. Let's see the step-by-step breakdown of the process:

 

Step 1: Identify the numerator and denominator because the numerator (81) will be taken as the dividend and the denominator (100) as the divisor.

 

Step 2: Since 81 is smaller than 100, it can't be divided directly. We will add a decimal to the quotient and make the number 810 by adding a zero to the dividend.

 

Step 3: Now that it is 810, we can divide it by 100. 100 goes into 810 eight times (since 100 × 8 = 800).

 

Step 4: Subtract 800 from 810, which gives 10.

 

Step 5: Bring down another 0 in the dividend place, making it 100, and repeat the division process. 100 goes into 100 once.

 

Step 6: The remainder is 0, and the division ends here.

 

The answer for 81/100 as a decimal is 0.81.
