The world of fractions and decimals can be complex and overwhelming, but what if we told you there's a way to simplify the process? In this article, we'll explore the concept of simplifying decimals, focusing on the 2/5 example. By the end of this article, you'll be able to simplify fractions and decimals with ease.
Why Simplify Decimals?
Simplifying decimals is essential in various mathematical operations, such as addition, subtraction, multiplication, and division. When decimals are simplified, it becomes easier to perform calculations and reduce errors. Moreover, simplifying decimals helps to reveal patterns and relationships between numbers, making it a crucial skill in mathematics and science.
What is 2/5 as a Decimal?
Before we dive into simplifying decimals, let's first convert the fraction 2/5 to a decimal. To do this, we divide the numerator (2) by the denominator (5).
2 ÷ 5 = 0.4
So, 2/5 as a decimal is 0.4.
How to Simplify 2/5 as a Decimal in 1 Step
Now, let's simplify 2/5 as a decimal in just one step. The key to simplifying decimals is to identify the common factors between the numerator and denominator. In this case, the numerator (2) and denominator (5) have no common factors other than 1.
However, we can simplify the decimal by observing that 2/5 is already in its simplest form. Since the numerator (2) is smaller than the denominator (5), the decimal equivalent 0.4 is also in its simplest form.
Therefore, the simplified decimal form of 2/5 is 0.4.
