Note that 9x3=27 so 27 is a multiple of 9. Now, 27 is also a multiple of itself since it is 27x1.So the LCM or least common multiple is 27.
Follow these steps:Step1* 12(225) = x•100Step2* Now multiply 12x225=2700 = 2700/100 (cross out the 2 zeros from top to bottom.) now were left to 27/1Step3* Then multiply x times 100 = 100x/100Step 4* Forget about the 100x/100Step5* The multiply 27x1 = 27The answer isx=27
