Fraction simplification RulesI am studying for GRE and One of the practice questions is a division. After converting my Mixed numeral I get 90 72 now I just have to simplify.What I understood is that you divide by Least common multiplier so I1.) Divide 90 72 by 2: And I got 45 36 2.) Divide 45 36 by 3: And I got 9 12 3.) and so on until I got to 3/4 which is the wrong answerIf in step 1, I would have divide by 31.) Divide 90 72 by 3 and I got 10 8 2.) Divide 10 8 by 2 and I got frac{5}{4} which is the right answerWhat is the rule to simplify fractions?
