Simplifying Fractions: 12/42 In Simplest Form

Quick Links :

Simplifying fractions is an essential skill in mathematics, as it allows us to express fractions in their most basic form, making calculations and comparisons easier. In this article, we will explore the concept of simplifying fractions, focusing on the example of 12/42.

The importance of simplifying fractions cannot be overstated. Simplified fractions are easier to understand, compare, and calculate with. They also help to avoid confusion and errors in mathematical operations. For instance, when adding or subtracting fractions, having them in their simplest form ensures that the results are accurate and reliable.

So, how do we simplify fractions? The process involves finding the greatest common divisor (GCD) of the numerator and the denominator, and then dividing both numbers by the GCD. This process reduces the fraction to its simplest form, where the numerator and denominator have no common factors other than 1.

Let's apply this process to the fraction 12/42.

Step-by-Step Simplification of 12/42

To simplify the fraction 12/42, we need to find the greatest common divisor (GCD) of 12 and 42.

Finding the Greatest Common Divisor (GCD)

The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.

The common factors of 12 and 42 are 1, 2, 3, and 6. The greatest common factor among these is 6.

Simplifying the Fraction

Now that we have found the GCD, we can simplify the fraction by dividing both the numerator and the denominator by the GCD.

12 ÷ 6 = 2 42 ÷ 6 = 7

So, the simplified form of the fraction 12/42 is 2/7.
