I dont think kris made a mistake Explanation: lets try solving a fraction using kris’s method. Fraction:120/50 common multiple for both numbers:10 we divide 120 by 10 and 50 by 10= 12/5. We cant find and common multiples so thats the final answer.(using kris’s method) if u try using a calculator u can see that the answer is 12/5 or 2.4. This means that kris’s method is not wrong
