What Is 30/42 as a Decimal + Solution With Free Steps
The fraction 30/42 as a decimal is equal to 0.714285714.
When converting Fractional quantities to Decimal values, the division operator is needed. The lower portion of the fraction is referred to as the Denominator, and the upper portion is known as the Numerator.
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 30/42.
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 = 30
Divisor = 42
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 = 30 $\div$ 42
This is when we go through the Long Division solution to our problem.
30/42 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 30 and 42, we can see how 30 is Smaller than 42, and to solve this division, we require that 30 be Bigger than 42.
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 30, which after getting multiplied by 10 becomes 300.
We take this 300 and divide it by 42; this can be done as follows:
300 $\div$ 42 $\approx$ 7
42 x 7 = 294
This will lead to the generation of a Remainder equal to 300 – 294 = 6. Now this means we have to repeat the process by Converting the 6 into 60 and solving for that:
60 $\div$ 42 $\approx$ 1
42 x 3 = 126
This, therefore, produces another Remainder which is equal to 60 – 42 = 18. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 180.
180 $\div$ 42 $\approx$ 4
42 x 4 = 168
Finally, we have a Quotient generated after combining the three pieces of it as 0.714=z, with a Remainder equal to 12.
