Finding the least common multiple (LCM) of the denominators and using it as the new denominator for each fraction will accomplish this.
Addition, subtraction, multiplication, and division are the fundamental operations of mathematics.
I’ll demonstrate the addition and subtraction of fractions to you in this essay. Hopefully, the pdf attached with this article will help your 5-7 (especially for 7th-grade students) grader kiddos to be familiar with the basic subtraction operation.
How to Add and Subtract Fractions Using Regrouping Methods
You must first identify a common denominator when adding or subtracting fractions with various denominators. To do this, determine the denominators’ least common multiples (LCM), then use that value as the new denominator for each fraction. If possible, you can add or subtract the numerators after finding a common denominator to simplify the resultant fraction. You must regroup the fraction or simplify it as a mixed number if the numerator is bigger than the denominator. Here’s an example of how to add and subtract fractions using regrouping: Add 2/3 and 5/4.
Find the least common multiple (LCM) of 3 and 4.
3, 6, 9, 12, 15, 18, 21, 24, 27, 30…
4, 8, 12, 16, 20, 24, 28, 32, 36…
The LCM of 3 and 4 is 12.
Convert each fraction to an equivalent fraction with a denominator of 12.
2/3 = 8/12 (multiply numerator and denominator by 4)
5/4 = 15/12 (multiply numerator and denominator by 3)
Add the numerators.
8/12 + 15/12 = 23/12
Simplify the fraction or regroup as a mixed number.
23/12 is an improper fraction, so we need to regroup it as a mixed number.
23/12 = 1 11/12
2/3 + 5/4 = 1 11/12.
When subtracting fractions using regrouping, the steps are similar, except you subtract the numerators in step 3 instead of adding them.
Regrouping in Fractions
Regrouping in fractions entails changing an improper fraction into a mixed fraction or vice versa.
A mixed number is a combination of a whole number and a fraction, while an improper fraction is a fraction in which the numerator is more than or equal to the denominator. Regrouping can aid in fraction addition, subtraction, multiplication, and division because it makes math simpler to comprehend and perform.
You can divide the numerator by the denominator of an improper fraction to get a mixed number. The mixed number’s whole number component is represented by the quotient and its numerator by the remainder. For instance, since 7/4 divides into 1 with a remainder of 3, the improper fraction can be reorganized as the mixed number 1 3/4.
You can multiply the entire number by the denominator and then add the numerator to transform a mixed number into an improper fraction.
The improper fraction’s numerator is the outcome, while the denominator stays the same. For example, the mixed number 2 1/3 can be regrouped as the improper fraction 7/3, since 2 times 3 is 6, and 6 plus 1 is 7.
When adding or subtracting fractions with dissimilar denominators, regrouping can also be utilized. In this situation, you must first identify a common denominator before converting each fraction to an equivalent fraction using that denominator. It could be necessary to regroup the result as a mixed number if the resultant fraction is incorrect.
3 Ways for Adding and Subtracting Fractions with Regrouping

Simple Fractions Regrouping
- This is just like the method described earlier.
- First take two fractions, like- ⅗ and ⅚. Let’s assume these two fractions to add.
- Now calculate the LCM of the two denominators.
- The LCM will be 30.
- Now divide the LCM with one denominator and multiply the numerator with the quotient.
- Do the same thing with the other fraction.
- Add both quotients together.
- If you find that the fraction is improper, make the fraction mixed.
- You will get the result after following the steps.
- You will also can subtract the fractions by subtracting the fractions instead of adding by this method.
Mixed Fraction Regrouping
- This method has similarities with the first activity.
- First, transform the mixed fraction into an improper fraction.
- Then, to add or subtract, follow the steps described in the former activity.
- After adding or subtracting, if the result shows any improper fraction, make the fraction mixed.
- Finish the activity.
Adding and Subtracting Fractions with Regrouping Bingo Game
- This is a board game.
- Roll the dice first.
- If anyone lands on a Bingo box, he or she will draw a card.
- He or she will solve the problems given in the card.
- If the problem is solved correctly, he or she will proceed with the game, otherwise, h or she will be stuck.
- The first one who completes the game will win the game.
