This selection of worksheets and lessons will help you find the area and perimeter of rectangles that contain measures with fractional sides. How to Multiply Fractions with Unlike Denominators Multiplication of unlike fractions with unlike denominators is considered difficult by many students, which shouldn't be the case at all. Let's try and understand how we can multiply fractions with unlike denominators. Let us take an example of distributing a pizza. One person grabs 1/3rd of the pizza, and now you are supposed to share the remainder of the pizza equally between two other individuals. What will the fraction be when divided between them? There are a few simple steps that need to be considered here. - Make an expression by setting up the problem. In this case, the expression will be: 1/2 of 1/3 = 1/2 x 1/3 (Unlike Denominators) The bottom numbers are different from each other. It can be a problem when you are adding or subtracting the fractions, but never when you are multiplying. - Multiply the top numbers with the numerator 1 x 1 = 1 (numerator for your answer) - Now multiply the denominators 2 x 3 = 6 (This will be your denominator) - Now put your answers together which will be = 1/6
