We have to find the greatest possible number of each type of flower ( pansies and daisies ) in each row. We have to find the GCF for 27 and 36. 27 = 9 * 3 36 = 9 * 4 So : GCF ( 27, 36 ) = 9 We will have 9 pansies in 3 rows and 9 daisies in 4 rows. Answer: The greatest possible number of pansies in each row is 9.
