 # What Is 80/81 as a Decimal + Solution With Free Steps

The fraction 80/81 as a decimal is equal to 0.9876543.

The three forms of Fractions are proper fractions, improper fractions, and mixed fractions. A form of p/q can be used to represent a Fraction. The line known as the Division line separates p from q, where p stands for the Numerator and q for the Denominator. Here, we are more interested in the division types that result in a Decimal value, as this can be expressed as a Fraction. We see fractions as a way of showing two numbers having the operation of Division between them that result in a value that lies between two Integers.

Now, we introduce the method used to solve said fraction to decimal conversion, called Long Division, which we will discuss in detail moving forward. So, let’s go through the Solution of fraction 80/81.

## Solution

First, we convert the fraction components, i.e., the numerator and the denominator, and transform them into the division constituents, i.e., the Dividend and the Divisor, respectively.

This can be done as follows:

Dividend = 80

Divisor = 81

Now, we introduce the most important quantity in our division process: the Quotient. The value represents the Solution to our division and can be expressed as having the following relationship with the Division constituents:

Quotient = Dividend $\div$ Divisor = 80 $\div$ 81

This is when we go through the Long Division solution to our problem. Figure 1

## 80/81 Long Division Method

We start solving a problem using the Long Division Method by first taking apart the division’s components and comparing them. As we have 80 and 81, we can see how 80 is Smaller than 81, and to solve this division, we require that 80 be Bigger than 81.

This is done by multiplying the dividend by 10 and checking whether it is bigger than the divisor or not. If so, we calculate the Multiple of the divisor closest to the dividend and subtract it from the Dividend. This produces the Remainder, which we then use as the dividend later.

Now, we begin solving for our dividend 80, which after getting multiplied by 10 becomes 800.

We take this 800 and divide it by 81; this can be done as follows:

800 $\div$ 81 $\approx$ 9

Where:

81 x 9 = 729

This will lead to the generation of a Remainder equal to 800 – 729 = 71. Now this means we have to repeat the process by Converting the 71 into 710 and solving for that:

710 $\div$ 81 $\approx$ 8

Where:

81 x 8 = 648

This, therefore, produces another Remainder which is equal to 710 – 648 = 62. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 620.

620 $\div$ 81 $\approx$ 7

Where:

81 x 7 = 567

Finally, we have a Quotient generated after combining the three pieces of it as 0.987=z, with a Remainder equal to 53. Images/mathematical drawings are created with GeoGebra.
