What Is 69/80 as a Decimal + Solution With Free Steps
The fraction 69/80 as a decimal is equal to 0.862.
Different methods are used for the representation of rational numbers. Fractional representation is the most widely used method. It is a numerical representation of part of the whole. The fraction 69/80 shows two numbers having an operation of division between them.
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 69/80.
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 = 69
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 = 69 $\div$ 80
This is when we go through the Long Division solution to our problem. The following figure shows the solution for fraction 69/80.
69/80 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 69 and 80, we can see how 69 is Smaller than 80, and to solve this division, we require that 69 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 69, which after getting multiplied by 10 becomes 690.
We take this 690 and divide it by 80; this can be done as follows:
690 $\div$ 80 $\approx$ 8
80 x 8 = 640
This will lead to the generation of a Remainder equal to 690 – 640 = 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
80 x 6 = 480
This, therefore, produces another Remainder which is equal to 500– 480 = 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
80 x 2 = 160
Finally, we have a Quotient generated after combining the three pieces of it as 0.862, with a Remainder equal to 40.
