Solving Algebraic Fractions | Algebra | Maths | FuseSchool

Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions. In part 1 we saw how to simplify, and add and subtract algebraic fractions. We discovered that algebraic fractions follow the same principles as numeric fractions. In this video we’re going to look at how to solve problems involving algebraic fractions. When solving, we could treat them as fractions and make the same denominator to add or subtract. But it’s much easier to cross multiply to get rid of the denominators completely, so this is the method we use in this video. Multiply up one denominator at a time, making sure you multiply every numerator. Do not miss any term out. Multiply EVERYTHING in the question. Quite often when solving algebraic fractions, we end up with quadratics which we need to factorise. This then means we might end up with two different values of x. As always in maths, it’s really good practice to go back and check your answers, but substituting them in. Our teachers and animators come together to make fun & easy-to-understand videos in Chemistry, Biology, Physics, Maths & ICT. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to see what else we have on offer. Comment, like and share with other learners. You can both ask and answer questions, and teachers will get back to you. These videos can be used in a flipped classroom model or as a revision aid.

Monoclonal Antibodies | Health | Biology | FuseSchool

Antibodies are the warriors inside our body. They are part of our immune system, recognising and fighting against bad foreign invaders, called antigens. Antibodies can bind to a broad range of antigens, and are produced by cells of the immune system, known as B-cells. To learn more about antibodies
