What Is 15/79 as a Decimal + Solution With Free Steps
The fraction 15/79 as a decimal is equal to 0.18987342.
Fractional representation is the most common form to represent rational numbers. They can also be represented in the form of ratio and decimal notation. The fraction 12/34 is a non-terminating decimal fraction.
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 15/79.
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 = 15
Divisor = 79
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 = 15 $\div$ 79
This is when we go through the Long Division solution to our problem. The following figure shows the long division:
15/79 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 15 and 79, we can see how 15 is Smaller than 79, and to solve this division, we require that 15 be Bigger than 79.
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 15, which after getting multiplied by 10 becomes 150.
We take this 150 and divide it by 79; this can be done as follows:
150 $\div$ 79 $\approx$ 1
79 x 1 = 79
This will lead to the generation of a Remainder equal to 150 – 79 = 71. Now this means we have to repeat the process by Converting the 71 into 710 and solving for that:
710 $\div$ 79 $\approx$ 8
79 x 8 = 632
This, therefore, produces another Remainder equal to 710 – 632 = 78. Now we must solve this problem to the Third Decimal Place for accuracy, so we repeat the process with dividend 780.
780 $\div$ 79 $\approx$ 9
79 x 9 = 711
Finally, we have a Quotient generated after combining the three pieces of it as 0.189=z, with a Remainder equal to 69.
