How Do You Solve an Equation With Fractions With Different Denominators Using Subtraction?
Note:
Looking for practice solving equations containing fractions? In this tutorial, you'll see how to first convert a mixed fraction to an improper fraction and then subtract fractions with unlike denominators in order to solve an equation. Be sure to check you answers so you KNOW it's correct!
Background Tutorials
-
Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

How Do You Find a Common Denominator and a Least Common Denominator?
This tutorial gives you some practice finding a common denominator and the least common denominator of three fractions. There's only one least common denominator, but there are many common denominators. This tutorial gives you one. Can you find another?

Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).

How Do You Evaluate an Algebraic Expression?
Plugging variables into an expression is essential for solving many algebra problems. See how to plug in variable values by watching this tutorial.

What is a Variable?
You can't do algebra without working with variables, but variables can be confusing. If you've ever wondered what variables are, then this tutorial is for you!

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!
