Since this expression is not an equation, it can't be "solved." The common denominator of these two fractions is the product of their denominators: In our example, we would multiply our complex fraction, (((1)/(x+3)) + x - 10)/(x +4 +((1)/(x - 5))), by ((x+3)(x-5))/((x+3)(x-5)). Complex Fractions – Explanation & Examples A fraction is made up of two parts: a numerator and a denominator; the number above the line is the numerator and the number below the line is the denominator. That's equal to (4)(4) = 16. Another kind of fraction is called complex fraction, which is a fraction in which the numerator or the denominator contains a fraction. This type of fraction is also known as a compound fraction. You can't "solve" this expression, but you can simplify it: (x/3) - (2) - (x) + (4/2) - (x/6) = (2x/6) - 2 - (6x/6) + (2) - (x/6) = [(2x - 6x - x) / 6] + (-2 + 2) = [(-5x) / 6] + 0 = -5x / 6. A fraction is nothing but a division of its numerator and its denominator. Practice: Simplify complex fractions. wikiHow is where trusted research and expert knowledge come together. Our numerator becomes 9/15 + 2/15, which equals 11/15. Note that dividing a fraction by a whole number is the same as multiplying the denominator by that whole number. There are two methods used to simplify such kind of fraction. Now that we know how to simplify our square roots, we can very easily simplify any complex expression with square roots in it. Some examples of complex fractions are: 6 7 3 3 4 5 8 x 2 5 6 To simplify a complex fraction, remember that the fraction bar means division. (2/7) multiplied by (1/14) equals 2/98 or 1/49. So, we can rewrite the fraction as a standard fraction division problem.
