What Is 13/80 as a Decimal + Solution With Free Steps

The fraction 13/80 as a decimal is equal to 0.162.

Two non-zero numbers p and q, when divide as p/q generate a Fraction, which is simplified by division. Here p is the numerator, and q is the denominator. While the number between the two is used to denote the division process.

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 13/80.

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 = 13

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 = 13 $\div$ 80

This is when we go through the Long Division solution to our problem, which can be seen in figure 1.

13/80 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 13 and 80, we can see how 13 is Smaller than 80, and to solve this division, we require that 13 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 13, which after getting multiplied by 10 becomes 130.

We take this 130 and divide it by 80; this can be done as follows:

 130 $\div$ 80 $\approx$ 1

Where:

80 x 1 = 80

This will lead to the generation of a Remainder equal to 130 – 80 = 50. Now this means we have to repeat the process by Converting the 50 into 500 and solving for that:

500 $\div$ 80 $\approx$ 6

Where:

80 x 6 = 480

This, therefore, produces another Remainder which is equal to 500 – 480 = 20. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 200.

200 $\div$ 80 $\approx$ 2

Where:

80 x 2 = 160

Finally, we have a Quotient generated after combining the three pieces of it as 0.162=z, with a Remainder equal to 40.
