Using prime factorization can help eliminate later steps of simplifying. Students who have a hard time using the LCM to make the denominator the same before adding or subtracting fractions can sometimes find the LCM by using prime factorization until they begin to see the patterns that allow these conversions and equivalent fractions more easily. Since not all students grasp the same concept the same way, it is important to show many methods to do the same thing as well as allowing students to work with the fractions and develop their own methods for solving.

i think of it' be (5/2*4) * (3/2*5) and then 5/2*2*2 * 3/2*5 = 15/80= 3/sixteen i'm unsure yet i think of you in basic terms element out the numbers u can. the 8 might nicely be factred to 2 cases 4 which will nicely be taken right down to 2 cases 2 cases 2. An the the ten in 3 tenths might nicely be factored right down to 5 cases 2. desire it facilitates.

It will allow you to reduce them to their lowest common denominator as prime numbers are those only divisible by one and themselves.
