How Do You Multiply Fractions with Unlike Denominators? One of the four basic arithmetic operations, multiplication, is tricky to understand for kids. However, if we look at this operation closely, there is not must we need to be scared about. When it comes to applying operations between fractions, multiplication is a much more straightforward operation in comparison to addition, subtraction, and division. So, there are two cases of multiplication of fractions. The first one is when both fractions have the same denominator, and the second case is when the fractions do not have the same denominators. While there is not much difference between the multiplication process in both cases, the unlike denominators can scar the students. Use this example to understand how you multiply fractions with unlike denominators. Example: Multiply 3/7 and 5/11 What you need to do here, multiply the numerator of the first fraction with the numerator of the second one. Do the same with the denominators. Multiply the denominator of the first fraction with that of the second fraction. (3×5) / (7×11) = 15/77 If the fraction can be further simplified, you need to reduce it to its simplest form. A collection of worksheets and lessons that shows you how to multiply unlike fractions.
