# 5/8 – 3/4 = 1/8 (How to Subtract Fractions)

Are you struggling with subtracting fractions? Don’t worry, it’s a common challenge for many people. One of the key factors in successfully subtracting fractions is ensuring that the denominators are the same. This can be tricky, but once you grasp the concept, it becomes much easier.

In this article, we will guide you through the process of subtracting two fractions: 5/8 and 3/4. We’ll show you step-by-step how to convert these fractions to have a common denominator, subtract the numerators and simplify your result.

By following our instructions and practicing with more examples, you’ll soon become an expert at subtracting fractions!

So let’s dive in!

## Understand the Basics of Subtracting Fractions

You’ll need to remember the basics of subtracting fractions if you want to know how to write 5/8-3/4. One common mistake people make when subtracting fractions is that they try to directly subtract the numerators and denominators without finding a common denominator first. This won’t work because you can’t subtract apples from oranges, as the saying goes.

To find a common denominator, you need to look for the smallest number that both denominators can divide into evenly. For example, if you’re trying to subtract 1/2 from 3/4, you would need to find a number that both 2 and 4 can divide into evenly â€“ in this case, it’s 4. Then, you would convert each fraction so that they have a denominator of 4: 1/2 becomes 2/4 and 3/4 stays the same.

Finally, you can subtract the two fractions by simply subtracting their numerators: (3-2)/4 = 1/4.

Understanding how to properly subtract fractions has real-life applications beyond just solving math problems. For example, if you’re following a recipe that serves six but only need enough for four people, knowing how much ingredients to use requires being able to properly add or subtract fractions.

Similarly, understanding how much paint or wallpaper is needed for a room also involves adding or subtracting fractional measurements of area. So while it may seem like an abstract concept at first glance, knowing how to properly subtract fractions is actually quite practical!

## Convert the Fractions to Have a Common Denominator

To convert fractions to a common denominator, we can use a simple method. This is important when subtracting fractions because we need the same size pieces to do the operation. Finding common denominators means finding a number that both the top and bottom of each fraction can be multiplied by so they are equivalent.

For example, to find a common denominator for 5/8 and 3/4, we can look at their denominators: 8 and 4. We want to find a number that both of them can be multiplied by to become equivalent. In this case, we can multiply 3/4 by 2/2 (which equals one) to get it into eighths.

So now we have:

5/8 – (3 x 2)/(4 x 2) = 5/8 – 6/8

The next step is simplifying the fractions if possible. In this case, since the numerator is larger than the denominator for both fractions, we cannot simplify further. We just need to subtract like terms:

5/8 – 6/8 = -1/8

So there you have it! By finding common denominators and simplifying where possible, we were able to successfully subtract two fractions with different denominators.

## Subtract the Numerators

Now we’re ready to subtract the numerators, bringing us one step closer to finding our final answer. This may seem straightforward, but there are some common misconceptions that can trip you up. Here are three things to keep in mind:

1. Remember that when you subtract fractions with different denominators, you need to first convert them to have a common denominator. In this case, we found a common denominator of 8 by multiplying the denominators 4 and 2.
2. When subtracting the numerators, it’s important to keep track of the signs. In this example, we have 5/8 minus -3/8 (remember that subtracting a negative is the same as adding). So we end up with 5/8 + 3/8 = 8/8.
3. Finally, simplify your answer if possible by reducing any common factors between the numerator and denominator. In this case, since both numbers are divisible by 8, our final answer simplifies to just 1.

Understanding how to subtract fractions is not only important for math class but also has real-world applications such as cooking or measuring ingredients in recipes where you might need to add or subtract fractional amounts of ingredients accurately. By understanding these steps thoroughly and avoiding common mistakes like forgetting to find a common denominator or misplacing signs during subtraction, you’ll build confidence in your mathematical abilities and make life easier when dealing with fractions!

## Simplify the Result

After simplifying the resulting fraction, we end up with 1. This means that the two fractions have cancelled each other out completely. It’s a common occurrence when subtracting fractions in real-life situations. It’s important to understand how to simplify fractions to avoid making mistakes.

There are some common misconceptions about subtracting fractions that can lead to errors. One of these is thinking that you should only subtract the numerators and leave the denominators unchanged. However, this is not correct as it doesn’t take into account the fact that the denominators represent different parts of a whole.

To simplify the result of 5/8 – 3/4, we need to find a common denominator for both fractions. In this case, it’s 8 since both denominators are multiples of it. We then convert both fractions into equivalent ones with an 8 denominator and proceed with subtraction as usual by subtracting their numerators.

(5-6)/8 = -1/8.

Finally, we simplify -1/8 by dividing both numerator and denominator by its greatest common factor (-1) resulting in its simplest form: 1/-8 or just -â…›.

## Practice with More Examples

As you practice subtracting fractions, you’ll come to realize that comparing fractions and finding common denominators are essential skills to make the process easier.

When working with fractions, it’s important to remember that the denominator represents the total number of equal parts in a whole, while the numerator represents how many of those parts are being considered.

To subtract 5/8 – 3/4, we first need to find a common denominator. In this case, we can convert both fractions into eighths by multiplying 3/4 by 2/2, giving us 6/8. Now that both fractions have the same denominator, we can subtract their numerators: (5-6)/8 = -1/8.

Remember to always simplify your answer by reducing any possible factors between the numerator and the denominator.

Practice makes perfect when it comes to mastering fraction subtraction. The more problems you work through, the better equipped you’ll be at recognizing patterns and finding common denominators quickly.

Keep in mind that there are different methods for finding common denominators, such as multiplying each fraction’s denominator by one another or identifying a multiple of both denominators. Find what works best for you and keep practicing until it becomes second nature!

## Frequently Asked Questions
