I am new to message boards so if this is the wrong place for this math puzzle, i do apologize.

My son brought home a puzzle that has my whole family stumped.

I need the answer to this puzzle... please! (Nod) Using numbers 1-9 only once must = 100 (must use same formula below)

__ / __ x __ + __ x __ x __ /__ + __ x __ =100

example: 8 / 1 x 3 + 4 x 2 x 5 / 9 + 7 x 6 = 228.6666

But i need it to = 100.

Thanks to anyone who can help. I will donate $10 to this site for your time. Thank you..... Oh and they all must be whole numbers in each space.

Sorry if I am not explaining it right.
