Before we look at how to remove particles, let’s do a quick review of the basic properties and terminology related to removing particles.

Before learning how to subtract parts, it’s important to know two basic terms (and how they differ):

How To Subtract Fractions

Definition: The highest number in a fraction is called the numerator. For example, the fraction 5/6 has 5 in the numerator.

Denominator: The lower number of a fraction is called the denominator. For example, the fraction 5/6 has a denominator of 6.

Again, the numerator is the top number of the fraction and the denominator is the bottom number. These ideas are shown in Figure 01 below. Although these two math terms are simple, it is important to understand and recognize the numerator and denominator of fractions in order to master fractional multiplication skills.

Here you go, and you’re ready to take the next step in mastering your partial removal. Next, you need to know when a part removal problem falls into one of the following two categories:

This concept may seem simple, but it is necessary to refresh your understanding because you must know whether the subtraction problems have the same or different names in order to find the correct solution.

Now that you have the important basic skills, you are ready to solve some problems with partial subtraction.

The first example of defragmenting is simple and straightforward, so it’s a good idea to start using our simple 3-step process for defragmenting. If you learn to apply these three steps to simple examples, you’ll be able to use the same steps to solve more complex problems in the future (since this step works on partial subtraction problems ).

Step 2: If the examples have the same denominator, go to step 3. If they have different denominators, find the common denominator.

Now let’s move on to another example of subtracting fractions with like numbers, and then we’ll move on to an example of subtracting fractions with like numbers.

In the next example, you will use the same 3-step method that you used in example #. 1, as follows:

In this case, the correct answer is 3/9, but this part can be simplified. Since both 3 and 9 are divisible by 3, 3/9 can be simplified to 1/3.

In this example, the fractions have different denominators (they are different). The ratio of the first part is 2 and the second part is 7.

Before proceeding to the third step, we need to find a number that the raters can divide equally. This is called the common.

A very simple and effective way to find the common number between two parts is to multiply the divisors together (ie multiply the first divisor by the second part and multiply the second divisor by the first part.

After the second step, you’ll see that the original question has changed and you’re working with the same part that has a common name, which means the heavy lifting is done and you can solve the problem with removing the numerators. and store the same number:

As in the last example, you need to find a common denominator because the fractions are different. You can find the common denominator by multiplying the denominator like this:

Subtracting like fractions involves finding the difference in the numerator (higher value) rather than changing the denominator (lower value).

Figuring out parts of different denominators requires you to find the common denominator, which is the value that divides both sides equally.

Fold: Combining 1/4 and 3/4 creates 4/4 (whole). Division: 8/8 consists of 2/8 and 6/8. In fourth grade, students begin adding and subtracting similar fractions, but they should only use models, pictures, and number lines to illustrate and simplify. In fifth grade, students are expected to add and subtract fractions of all kinds (true, false, different names, etc.).

With a solid foundation in addition and subtraction, division, comparison, naming like parts, and understanding the relationship between certain parts (such as half/quarter/eighths/sixths) ten; and third / ninth / sixth / twelfth; or fifth / tenth) students are more willing to do partial work.

Appraisal: An important part of operating a part. Do you expect your answer to be less than 1/2, more than 1/2, more than 1? How do you know? If I add 8/9 + 11/12, my answer should be about _____? It should be less than 2 because both parts are close to 1.

If I add 4/6 and 6/8, my answer should be greater than 1 because each of these fractions is greater than 1/2.

Different strategies:  There are many “tricks” or shortcuts to show students how to quickly add, subtract, or multiply fractions. I believe that these shortcuts are only useful when students understand why and how to find common denominators and their equivalent fractions. These abbreviations do not help in building a conceptual understanding of fractions. I will focus on how to understand

How To Add And Subtract Fractions With Different Denominators

Adding or subtracting fractions with the same number: Use objects and pictures to show students that 1/4 + 1/4 is NOT 2/8. Share the whole with this model. Remember the best way to learn: concrete and visual rather than abstract.

Adding fractions with different denominators: Read my previous article Fractions Part 2 about making fractions, especially using bars or rectangles. This is a basic skill for creating equivalent fractions (which is needed to add fractions with different denominators). Although it can be tiring to draw pictures for every addition or subtraction problem, I recommend it to introduce the concept so that the students can see again that multiplying parts of the representative of 1 ( 2/2, 3/3, etc.). .) Naming equal parts does not change the shaded part (to make it easier to add or remove), but divides the shaded part into smaller parts. Remember that dividing a whole number by 1 doesn’t change the result – it’s the same idea about fractions.

Simplification Section: I mentioned this in Part 5, but here it is again. As students practice more, they should begin to learn the relationship between some common fractions (to make thirds you can start with half or fourths; to make sixths or thirds you can starting with a third, etc.). To simplify, use the reverse process to remove lines from the split shape.
