Introduction

In mathematics, fractions and decimals are two ways to represent numbers. A fraction is a way to show a part of a whole, while a decimal is a way to show a number in a base-10 system. In this article, we will focus on expressing fractions as decimals, specifically the fraction 36/144.

Understanding the Fraction 36/144

Before we can express the fraction 36/144 as a decimal, we need to understand what the fraction represents. The fraction 36/144 can be read as "36 out of 144." This means that 36 is the numerator (the top number) and 144 is the denominator (the bottom number).

Simplifying the Fraction

To simplify the fraction 36/144, we need to find the greatest common divisor (GCD) of the numerator and the denominator. The GCD is the largest number that divides both numbers without leaving a remainder.

import math

def gcd(a, b):
    while b != 0:
        a, b = b, a % b
    return a

numerator = 36
denominator = 144
gcd_value = gcd(numerator, denominator)

simplified_numerator = numerator // gcd_value
simplified_denominator = denominator // gcd_value

print(f"Simplified fraction: {simplified_numerator}/{simplified_denominator}")

The GCD of 36 and 144 is 36. Therefore, the simplified fraction is 1/4.

Expressing the Fraction as a Decimal

To express the fraction 1/4 as a decimal, we can use the following formula:

Decimal = Numerator / Denominator

In this case, the numerator is 1 and the denominator is 4.

decimal_value = 1 / 4
print(f"Decimal value: {decimal_value}")

The decimal value of 1/4 is 0.25.

Conclusion

In this article, we learned how to express the fraction 36/144 as a decimal. We simplified the fraction by finding the greatest common divisor (GCD) of the numerator and the denominator, and then used the formula Decimal = Numerator / Denominator to express the fraction as a decimal. The decimal value of 36/144 is 0.25.

Real-World Applications

Expressing fractions as decimals has many real-world applications. For example, in cooking, a recipe may call for 1/4 cup of sugar. In this case, the fraction 1/4 can be expressed as a decimal, 0.25, to make it easier to measure the correct amount of sugar.

Common Mistakes
