Answer» The number of chairs will need to be a multiple of 27 (so they can have “m” rows of 27 chairs each, for a TOTAL of 27M chairs) and also a multiple of 33 (so they can have “n” rows of 33 chairs each, for a total of 33N chai If you SET 27m equal to the LCM, what value do you get for “m”? (This is the number of 27-chairs-each rows you can get.) If you get 33n equal to the LCM, what value do you get for “n”? (This is the number of 33-chairs-each rows you can get.) Note: This is only the SMALLEST number of chairs for which you can set up the chairs in the stipulated manner. Any multiple of the LCM will work, also. |
