yeah - i thought it was too good to be true in class yesterday. thanks so much for the help. i found another thing on this site searching around after i posted (love this site as a resource) that said
30 monkeys laughed at 1 old zebra
8 dozen roses, 2 turkey, 6 tums
30 ml = 1 oz = 8 dr = 2 t = 6 t
thank you so much for the input. i really appreciate it. now i know to really scrutinize shortcuts in math before i try to put them to practice.
