  LCM of 9 and 12 To find out LCM (Least common multiple) of 9 and 12 ,we will follow the following methods.         Method-01: Step-1:Find out the multiples of 9 and 12 first. *Multiples of 12 •12×1= 12 •12×2=24 •12×3= 36 •12×4= 48 ....................... *So the multiples of 12 are 12,24,36,48.....etc. *Multiples of 9 •9×1=9 •9×2=18 •9×3=27 •9×4=36 •9×5 =45 ..................... *So the multiples of 9 are 9,18,27,36, 45....etc Step-2:LCM (Least common multiple) of 9 and 12 means that the smallest multiple that both number (9 and 12) share. So in this step we will identify the smallest multiple that both number share or that is common in both number. *M ultiples of 12 are 12,24, 36 ,48.....etc. *M ultiples of 9 are 9, 18 ,27, 36 , 45....etc Therefore,the smallest multiple that both number (9 and 12) share is 36. Answer:The LCM or least common multiple of 9 and 12 is 36.

  LCM of 6 and 9 To find out LCM (Least common multiple) of 6 and 9 ,we will follow the following methods.         Method-01: Step-1:Find out the multiples of 6 and 9 first. *Multiples of 6 •6×1=6 •6×2=12 •6×3=18 •6×4=24 •6×5=30 •6×6=36 •6×7 =42 .................. *So the multiples of 6 are 6,12,18,24,30,36,42.....etc. *Multiples of 9 •9×1=9 •9×2=18 •9×3=27 •9×4=36 •9×5 =45 ..................... *So the multiples of 9 are 9,18,27,36, 45....etc Step-2:LCM (Least common multiple) of 6 and 9 means that the smallest multiple that both number (6 and 9) share. So in this step we will identify the smallest multiple that both number share or that is common in both number. *M ultiples of 6 are 6,12, 18 ,24,30 ,36, 42.....etc . *M ultiples of 9 are 9, 18 ,27, 36 , 45....etc Therefore,the smallest multiple that both number (6 and 9) share is 18. Answer:The LCM or least common multiple of 6 and 9 is 18.

  LCM of 4 and 6 To find out LCM (Least common multiple) of 4 and 6 ,we will follow the following methods.         Method-01: Step-1:Find out the multiples of 4 and 6 first. *Multiple of 6 •6×1=6 •6×2=12 •6×3=18 •6×4=24 •6×5=30 •6×6=36 .................. *So the multiples of 6 are 6,12,18,24,30,36.....etc. *Multiple of 4 •4×1=4 •4×2=8 •4×3=12 •4×4=16 ..................... *So the multiples of 4 are 4,8,12,16,....etc. Step-2:LCM (Least common multiple) of 4 and 6 means that the smallest multiple that both number (4 and 6) share. So in this step we will identify the smallest multiple that both number share or that is common in both number. *Multiples of 6 are 6, 12 ,18, 24 ,30,36.....etc . *Multiples of 4 are  4,8, 12 ,16,....etc Therefore,the smallest multiple that both number (4 and 6) share is 12. Answer:The LCM or least common multiple of 4 and 6 is 12. Next

LCM of 6 and 8 To find out LCM (Least common multiple) of 6 and 8 ,we will follow the following methods.         Method-01: Step-1:Find out the multiples of 6 and 8 first. *Multiple of 6 •6×1=6 •6×2=12 •6×3=18 •6×4=24 •6×5=30 •6×6=36 .................. *So the multiples of 6 are 6,12,18,24,30,36.....etc. *Multiple of 8 •8×1=8 •8×2=16 •8×3=24 •8×4=32 ..................... *So the multiples of 8 are 8,16,24,32,....etc Step-2:LCM (Least common multiple) of 6 and 8 means that the smallest multiple that both number (6 and 8) share. So in this step we will identify the smallest multiple that both number share or that is common in both number. *Multiples of 6 are 6,12,18, 24 ,30,36.....etc. *Multiples of 8 are 8,16, 24 ,32,....etc Therefore,the smallest multiple that both number (6 and 8) share is 24. Answer:The LCM or least common multiple of 6 and 8 is 24.

2 1/4 as an improper fraction           Step-1:  2 1/4 is a mixed number.It has two parts.One is whole number which is 2 and the other part is fraction which is 1/4.             Step-2 : To convert mixed number to improper fraction,you have to use the following formula: (Whole number ×Denominator of fraction+ Numerator of fraction)/Denominator of fraction          Step-3: 2 1/4 as an improper fraction   2 1/4 =(2×4+1)/4 =(8+1)/4 =9/4(Answer) ●9/4 is an improper fraction because numerator is greater than denominator.
