1 3 Plus 1 3: A Simple but Effective Math Trick
Mathematics can be challenging for many people, but there are some simple tricks that can make calculations easier and faster. One such trick is the 1 3 plus 1 3 method, which is a quick way to add or subtract fractions with the same denominator. In this post, we will explain what the 1 3 plus 1 3 method is, how it works, and why it is useful.
What is the 1 3 Plus 1 3 Method?
The 1 3 plus 1 3 method is a mathematical shortcut for adding or subtracting fractions with the same denominator. It is called the 1 3 plus 1 3 method because it involves adding or subtracting one-third of a fraction from itself. For example, if you have two fractions with the same denominator, say 3/4 and 5/4, you can use the 1 3 plus 1 3 method to add them quickly.
How Does the 1 3 Plus 1 3 Method Work?
The 1 3 plus 1 3 method works by breaking down the fractions into smaller, simpler parts. To use this method, you need to follow a few simple steps:
Step 1: Write down the fractions you want to add or subtract.
Step 2: Identify the common denominator of the fractions. This is the number that appears at the bottom of each fraction.
Step 3: Divide the common denominator by 3.
Step 4: Add or subtract one-third of the denominator from each fraction.
Step 5: Simplify the resulting fractions if necessary.
Let's illustrate this method with an example. Suppose we want to add the fractions 2/5 and 3/5. Here is how we can use the 1 3 plus 1 3 method:
Step 1: Write down the fractions: 2/5 + 3/5.
Step 2: Identify the common denominator: 5.
Step 3: Divide the denominator by 3: 5 ÷ 3 = 1.66 (rounded up to 2).
Step 4: Add one-third of the denominator to each fraction: 2/5 + 2/5 + 3/5 - 2/5.
Step 5: Simplify the resulting fractions: 4/5 + 1/5 = 5/5 = 1.
Therefore, the sum of 2/5 and 3/5 is 1, which we could have obtained by adding the fractions directly, but the 1 3 plus 1 3 method provides a quicker way to do it.
Why is the 1 3 Plus 1 3 Method Useful?
The 1 3 plus 1 3 method is useful because it simplifies the process of adding or subtracting fractions. It is particularly helpful when dealing with fractions that have large denominators or when you need to perform calculations quickly. The method can be used for any fractions with the same denominator, not just thirds. Moreover, the 1 3 plus 1 3 method can be used in combination with other methods of fraction arithmetic, such as finding a common denominator or converting mixed numbers to improper fractions.
Conclusion
The 1 3 plus 1 3 method is a simple but effective way to add or subtract fractions with the same denominator. It involves breaking down the fractions into smaller parts and adding or subtracting one-third of the denominator from each fraction. This method can save time and simplify calculations when dealing with fractions. While it may not be suitable for all situations, it is a useful trick to have in your mathematical toolkit.
