Reducing fractions is a great way to recollect earlier learnt concepts in math like fractions and divisions. The more 7th graders practice mixed fractions the more they become adept at solving advanced math problems accurately and fast. A fraction is reduced to lowest terms, or simplified, when its numerator and denominator have no common factors. This makes it easy to multiply, add, divide or subtract fractions in lengthy math problems. Check out the math worksheet for 7th grade and test the skills!
