This educational worksheet introduces students to subtracting fractions with non-matching denominators. Following an example, students have eight subtraction challenges to solve. The worksheet concludes with a real-life word problem.

The example shows how to solve 2/7 - 1/5. First, you must find a common denominator to subtract the fractions easily. Since 7 and 5 don't have the same denominator, we find a number they both can divide into. We find the least common multiple of 7 and 5, which is 35. Now, change each fraction to have a denominator of 35. Multiply 2/7 by 5/5 to get 10/35, and multiply 1/5 by 7/7 to get 7/35. You are now ready to solve the equation: 10/35 - 7/35 = 3/35. So, the answer is 3/35!
