What Is 18/90 as a Decimal + Solution With Free Steps

The fraction 18/90 as a decimal is equal to 0.2.

Fractions are simply another way of representing the division of a number p (dividend) by another number (divisor). usually, we represent division as p $\boldsymbol\div$ q, but in fractions, we represent this as p/q, where p is the numerator and q is the denominator.

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 18/90.

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 = 18

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 = 18 $\div$ 90

This is when we go through the Long Division solution to our problem.

We start solving a problem using the Long Division Method by first taking apart the division’s components and comparing them. As we have 18 and 90, we can see how 18 is Smaller than 90, and to solve this division, we require that 18 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 18, which after getting multiplied by 10 becomes 180.

We take this 180 and divide it by 90; this can be done as follows:

 180 $\div$ 90 = 2

Where:

90 x 2 = 180

This leads to a zero remainder. Thus, we have a Quotient of 0.2, with a Remainder equal to 0.
