What Is 36/80 as a Decimal + Solution With Free Steps

The fraction 36/80 as a decimal is equal to 0.45.

A mixed fraction is one type of fraction which consist of a whole number and a proper fraction. A mixed fraction is converted into a simple improper fraction by multiplying the whole number with the denominator and then adding the numerator of the proper fraction with the answer. A new fraction is obtained with the same 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 36/80.

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 = 36

Divisor = 80

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 = 36 $\div$ 80

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 36 and 80, we can see how 36 is Smaller than 80, and to solve this division, we require that 36 be Bigger than 80.

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 36, which after getting multiplied by 10 becomes 360.

We take this 360 and divide it by 80; this can be done as follows:

 360 $\div$ 80 $\approx$ 4

Where:

80 x 4 = 320

This will lead to the generation of a Remainder equal to 360 – 320 = 40. Now this means we have to repeat the process by Converting the 40 into 400 and solving for that:

400 $\div$ 80 = 5 

Where:

80 x 5 = 400

Therefore  Remainder which is equal to 400 – 400 = 0. Now we stop solving this problem, we have a Quotient generated after combining the two pieces of it as 0.45=z, with a Remainder equal to 0.
