How Do You Add Fractions with Different Denominators?
Note:
Trying to add fractions with unlike denominators? You're going to need a common denominator first! Follow along with this tutorial and see what you need to do to add these fractions together.
Background Tutorials
-
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!

Further Exploration
-
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.
