How To Calculate 1.8 out Of 2 As a Percentage?

Calculating percentages is a fundamental skill that helps us understand proportions and scores in a relatable way.

When you get a score in a test or an assignment, it’s often given as a fraction, like getting 1.8 out of 2 marks.

To really grasp how well you’ve done and to compare it with grading scales, it’s very useful to convert this fraction into a percentage.

This guide will take you through a simple, step-by-step method to calculate what percentage 1.8 is out of 2.

By the end of this guide, you’ll not only be able to calculate this specific example but also understand the general process of converting any fraction into a percentage.

Here are the steps we’ll follow:

Step 1: Understand the “Out Of” Concept and Formulate a Fraction

The phrase “1.8 out of 2” tells us exactly what we need to know to start our calculation.

It means you have achieved a score of 1.8 marks from a total possible score of 2 marks.

Think of it like this:

• The “Out Of” part (2) is the total or the whole amount. This is the maximum score you could have gotten. In mathematical terms, this is called the denominator of a fraction.
• The “1.8” part is the score you actually achieved or the part you have. This is the portion of the whole. In mathematical terms, this is called the numerator of a fraction.

To begin calculating the percentage, we first need to express “1.8 out of 2” as a fraction.

A fraction simply represents a part of a whole.

So, the fraction becomes:

Numerator (Part you have) / Denominator (Total possible)

In our example, this is:

1.8 / 2

This fraction, 1.8 divided by 2, is the starting point for finding our percentage.

Step 2: Perform the Division to Get a Decimal

The next step is to divide the numerator (1.8) by the denominator (2). This division will give us a decimal number.

A decimal is just another way to represent a part of a whole, often making it easier to convert to a percentage.

Let’s perform the division:

1.8 ÷ 2 = ?

If you do this calculation, you will find that:

1.8 ÷ 2 = 0.9

So, 0.9 is the decimal form of the fraction 1.8/2. This decimal tells us the proportion of the whole that 1.8 represents.

Step 3: Convert the Decimal to a Percentage by Multiplying by 100

A percentage literally means “out of one hundred.” To convert our decimal (which represents a proportion out of one whole) into a percentage (which represents a proportion out of one hundred), we need to multiply our decimal by 100.

So, we take our decimal, 0.9, and multiply it by 100:

0.9 × 100 = ?

Performing this multiplication gives us:

0.9 × 100 = 90

This number, 90, is the percentage. To show that it’s a percentage, we add the percentage symbol (%) after the number.

Therefore, 1.8 out of 2 as a percentage is 90%.
