# What Is 18/80 as a Decimal + Solution With Free Steps

The fraction 18/80 as a decimal is equal to 0.225.

Fractions are alternate notations for division. They have the form of a numeral p/q, where p (the dividend) is called the numerator and q (the divisor) is called the denominator. A fraction has the same properties and evaluation process as a simple division and produces either an integer or decimal as the result.

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 18/80.

## 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 = 18

Divisor = 80

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 = 18 $\div$ 80

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

## 18/80 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 18 and 80, we can see how 18 is Smaller than 80, and to solve this division, we require that 18 be Bigger than 80.

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 18, which after getting multiplied by 10 becomes 180.

We take this 180 and divide it by 80; this can be done as follows:

180 $\div$ 80 $\approx$ 2

Where:

80 x 2 = 160

This will lead to the generation of a Remainder equal to 180 – 160 = 20. Now this means we have to repeat the process by Converting the 20 into 200 and solving for that:

200 $\div$ 80 $\approx$ 2

Where:

80 x 2 = 160

This, therefore, produces another Remainder which is equal to 200 – 160 = 40. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 400.

400 $\div$ 80 $\approx$ 5

Where:

80 x 5 = 400

Finally, we have a Quotient generated after combining the three pieces of it as 0.225, with a Remainder equal to 0.
