How Do You Subtract Mixed Fractions with Different Denominators by Regrouping?
Note:
Subtracting mixed fractions with unlike denominators? You could first find a common denominator and use it to rewrite each fraction. Then, subtract the whole numbers and fractions separately. In this tutorial, take a look at subtracting mixed fractions with unlike denominators!
Background Tutorials
-
Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.
-
What's a Mixed Number?
Fractions come in all sorts of flavors, and in this tutorial you'll learn how to recognize mixed numbers.
-
-
Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.
-
How Do You Add Fractions with the Same Denominator?
While adding fractions can be hard, adding fractions with the same denominator is just as easy as adding numbers. That's why when you add fractions you first get all of them to have the same denominator, and then add them up. In this tutorial you get to see just how easy it is to add up fractions once they have the same denominator!

Understand subtraction of rational numbers as adding the additive inverse, p - q = p + (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.

How Do You Subtract Fractions with the Same Denominator?
Subtracting fractions with like denominators? Just subtract the numerators and put the result over the common denominator! To see this process in action, check out this tutorial!

Further Exploration
-
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators.

How Do You Add Mixed Fractions with Different Denominators by Converting to Improper Fractions?
Adding mixed fractions? You could first convert each to an improper fraction. If they don't have common denominators, then find a common denominator and use it to rewrite each fraction. Then, add the fractions together and simplify. In this tutorial, take a look at adding together mixed fractions with unlike denominators!
