The Algebrator Software is marvelous. Complex numbers always scared me and I wanted a way out. The step-by-step way of your software really cleared my concepts and now I look forward to solve other types of algebra problems. Brian Phillips, WI ...
Students will use unit squares to add fractions with unlike denominators. Recall why it is possible to add the two fractions when the denominators are the same. What is the teacher doing? Finding a least common denominator is not necessary and, in fact, can lead to confusion for students, o...

Adding fractions with the same denominator is quite simple: just add the numerators and keep the denominator. The only thing that can make this process more difficult is if the result needs to be simplified, or if it is necessary to convert the result into a mixed number. An example of ...
Do you dread teachingadding fractions with unlike denominators? Does the thought ofworking on mixed numbersmake you frown? Well, it doesn’t have to be hard and it doesn’t have to be boring. In fact, with a little practice, your children can beadding fractionswithout pencil and paper. No...
Step 1:Check whether the given fractions are like or unlike fractions. Find out whether the denominators are the same. Step 2:If the denominator is the same, find the sum of the numerators and place the sum over the common denominator. Simplify the final fraction if required. ...
What are the rules for adding fractions with like denominators? Here are the steps to follow when adding fractions with like denominators: Change mixed numbers to improper fractions if needed. Add the numerators. Write the new numerator over the denominator. Put the sum in its lowest terms. Th...
Adding Fractions with Unlike Denominators Find a common denominator. Rewrite each fraction using the common denominator. Now that the fractions have a common denominator, you can add the numerators. Simplify by canceling out all common factors in the numerator and denominator....
fractions with unlike denominators, developing fluency in adding and subtracting fractions. This is identified as Critical Area 1 in the 2011 Massachusetts Curriculum Frameworks for Mathematics. Students will be using improper fractions and mixed numbers in these applications, often switching between those...
To add mixed numbers with the different denominators: Add the whole number parts. Change the fractions as required to their equivalent values so all fractions have the same denominator. Add or subtract the numerators. Leave the denominator as is.Adding...
