0.18 As A Fraction In Simplest Form

Quick Links :

In today's world, decimals and fractions are used extensively in various fields, including mathematics, science, engineering, and finance. While decimals are commonly used in many applications, fractions are still an essential part of many mathematical and real-world problems. In this article, we will explore how to convert the decimal 0.18 to a fraction in its simplest form.

The importance of converting decimals to fractions lies in the fact that fractions provide a more precise representation of certain values, especially when dealing with proportions, ratios, and mathematical operations. Moreover, fractions are often required in specific mathematical contexts, such as algebra, geometry, and calculus.

Converting Decimals to Fractions

Converting decimals to fractions is a straightforward process that involves a few simple steps. To convert a decimal to a fraction, we can use the following steps:

1. Write the decimal as a fraction with the decimal part as the numerator and the place value of the last digit as the denominator.
2. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).

Converting 0.18 to a Fraction

To convert 0.18 to a fraction, we can follow the steps outlined above.

First, we write 0.18 as a fraction with the decimal part as the numerator and the place value of the last digit as the denominator:

0.18 = 18/100

Next, we simplify the fraction by dividing both the numerator and denominator by their GCD. In this case, the GCD of 18 and 100 is 2. Therefore, we can simplify the fraction as follows:

18 ÷ 2 = 9 100 ÷ 2 = 50

So, the simplified fraction is:

0.18 = 9/50
