Answer 2

we can write 5.5=11/2

this means 3 numbers are 2 ,4,11/2 or we can say 1/2, 1/4, 2/11(because taking LCM of fraction no and natural number is not convinient)

we know that LCM OR FRACTION =LCM OF NUMIRATER /HCF OF DENOMINATER

THIS MEANS,LCM OF 2,4,11 =44

HCF OF 1,1,2=1

THEREFORE, LCM =44
