What Is 16/81 as a Decimal + Solution With Free Steps
The fraction 16/81 as a decimal is equal to 0.197.
Rational numbers are numbers that can be expressed in the form of ratios. It is a fraction in which the numerator and denominator are polynomials and represent real numbers. We get Terminating and Recurring decimals when we divide a rational 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 16/81.
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 = 16
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 = 16 $\div$ 81
This is when we go through the Long Division solution to our problem.
16/81 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 16 and 81, we can see how 16 is Smaller than 81, and to solve this division, we require that 16 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 16, which after getting multiplied by 10 becomes 160.
We take this 160 and divide it by 81; this can be done as follows:
160 $\div$ 81 $\approx$ 1
81 x 1 = 81
This will lead to the generation of a Remainder equal to 160 – 81 = 79. Now this means we have to repeat the process by Converting the 70 into 790 and solving for that:
790 $\div$ 81 $\approx$ 9
81x 9 = 729
This, therefore, produces another Remainder which is equal to 790 – 729= 61. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 610.
610 $\div$ 81 $\approx$ 7
81x 7 = 567
Finally, we have a Quotient generated after combining the three pieces of it as 0.197=z, with a Remainder equal to 43.
