Length of a string

What is the smallest length of a string that we can cut into 18 equal parts and even 27 equal parts (in decimeters)?

Correct result:

x =  54 dm

Solution:

18=232 27=33 LCM(18,27)=233=54  x=LCM(18,27)=54 dm



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
