Year Eight Math Worksheet for Kids – Addition of RAEs with Different Denominators

Year Eight Mathematics Worksheets

Mathematics can be a challenging subject for kids, especially when they are learning about algebraic expressions. However, with the right resources and guidance, it can also be an exciting and rewarding subject. In this article, we’ll be focusing on the addition of rational algebraic expressions (RAEs) with different denominators.

A rational algebraic expression is a fraction that contains variables. When we add two RAEs, we need to make sure that they have the same denominators, so that we can combine them like regular fractions. However, if the RAEs have different denominators, we need to follow a different procedure.

To add two RAEs with different denominators, we first need to find a common denominator. The common denominator should be a multiple of both the original denominators, and it should be the smallest possible number that fits that description. To find the common denominator, we simply multiply the two denominators together.

Next, we need to convert each RAE into an equivalent expression that has the common denominator. We do this by multiplying both the numerator and denominator of each fraction by the same number, so that the fraction remains the same but with a different denominator.

Finally, once both RAEs have the same denominator, we can add them like any other fraction. To do this, we simply add the numerators together, while keeping the same denominator. This gives us the answer in the form of a fraction.

It is important to note that when adding RAEs with different denominators, we may also need to simplify the answer by dividing the numerator and denominator by the greatest common factor. This is to make sure that the answer is in its simplest form.

In conclusion, adding RAEs with different denominators is a crucial step in understanding algebraic expressions and solving mathematical problems. With the right resources and guidance, kids can master this skill and move on to more advanced topics in mathematics. So keep practicing and don’t be afraid to ask for help when needed!
