The world of fractions! Simplifying fractions can be a daunting task, but fear not, dear reader, for we're about to break it down into 5 easy steps. In this article, we'll take the fraction 30/56 and simplify it to its lowest terms.
What is Simplifying Fractions?
Before we dive into the steps, let's quickly review what simplifying fractions means. Simplifying a fraction involves finding an equivalent fraction with the smallest possible numerator and denominator. This is also known as reducing a fraction to its lowest terms.
Step 1: Find the Greatest Common Divisor (GCD)
The first step in simplifying a fraction is to find the greatest common divisor (GCD) of the numerator and denominator. The GCD is the largest number that divides both numbers evenly.
In our case, we need to find the GCD of 30 and 56.
Method to Find GCD
One way to find the GCD is to list the factors of each number and find the largest common factor.
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30 Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
The largest common factor is 2.
Step 2: Divide Both Numbers by the GCD
Now that we have the GCD, we can simplify the fraction by dividing both the numerator and denominator by the GCD.
Numerator: 30 ÷ 2 = 15 Denominator: 56 ÷ 2 = 28
So, our simplified fraction is now 15/28.
Why Divide by the GCD?
Dividing both numbers by the GCD ensures that we're reducing the fraction to its simplest form. By doing so, we're essentially canceling out any common factors between the numerator and denominator.
Step 3: Check for Further Simplification
After dividing both numbers by the GCD, we need to check if the fraction can be simplified further. This involves finding the GCD of the new numerator and denominator.
In our case, we need to find the GCD of 15 and 28.
Method to Find GCD (Again)
Using the same method as before, we can find the factors of each number and identify the largest common factor.
Factors of 15: 1, 3, 5, 15 Factors of 28: 1, 2, 4, 7, 14, 28
The largest common factor is 1.
Step 4: Check for Any Other Common Factors
If the GCD is 1, it means that the numerator and denominator have no common factors other than 1. In this case, we can conclude that the fraction is already in its simplest form.
However, if the GCD is not 1, we would need to repeat the process of dividing both numbers by the GCD until we reach a GCD of 1.
Step 5: Write the Simplified Fraction
The final step is to write the simplified fraction. In our case, we've already simplified the fraction to 15/28, and we've confirmed that it's in its simplest form.
So, the simplified fraction of 30/56 is indeed 15/28.
And there you have it! Simplifying fractions in 5 easy steps.
