What Is 12/90 as a Decimal + Solution With Free Steps

The fraction 12/90 as a decimal is equal to 0.133333.

Mathematics equations are based on some operators by simplifying the equation, we get some values or either expression. Similarly, fraction expression is a mathematical equation in which a division operator is used and simplified through the long division method as a result will get a decimal value.

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 12/90.

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 = 12

Divisor = 90

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 = 12 $\div$ 90

This is when we go through the Long Division solution to our problem. The following figure shows the long division:

We start solving a problem using the Long Division Method by first taking apart the division’s components and comparing them. As we have 12 and 90, we can see how 12 is Smaller than 90, and to solve this division, we require that 12 be Bigger than 90.

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 12, which after getting multiplied by 10 becomes 120.

We take this 120 and divide it by 90; this can be done as follows:

 120 $\div$ 90 $\approx$ 1

Where:

90 x 1 = 90

This will lead to the generation of a Remainder equal to 120 – 90 = 30. Now this means we have to repeat the process by Converting the 30 into 300 and solving for that:

300 $\div$ 90 $\approx$ 3 

Where:

90 x 3 = 270

This, therefore, produces another Remainder which is equal to 300 – 270 = 30. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 300.

300 $\div$ 90 $\approx$ 3 

Where:

90 x 3 = 270

Finally, we have a Quotient generated after combining the three pieces of it as 0.133=z, with a Remainder equal to 30.
