The 9 numbers and 7 Xs of the set (1,2,3,4,5,6,7,8,9,X,X,X,X,X,X,X ) were placed in a 4x4 grid to create a matrix as follows:

**
X 4 8 9 **

5 6 X 7

1 X X X

3 2 X X

Consider the Xs as black squares in a crossword and evaluate the sum of the sums taken per row:

** S**_{r}=489+(56+7)+1+32=585.
Same operation per column:

** S**_{c}= 513+(46+2)+8+97=666
Evaluate the ratio

** r= S**_{r}/ S_{c}=585/666= 0.878378...
Your task :

Distribute the 9 non-zero digits and 7 black squares in a 4x4 grid so

that
the ratio **r**, calculated as in the example above will be as close

to the value of pi (=3.14159265…) as possible.

Ha**PP**y **P**i day, every **P**erson.

I've spent exactly 45 min, trying to get close to PI, using only one of C(16,7) possible *crossword forms* and using common sense and calculator only.

I stop at **3.13888888... i.e, 0.086% error.**

My (so far the only) solution should be a yardstick, so only the distributions of numbers and X's that produce a ratio** r** closer to **PI** should be submitted**. **

**(2987+3+1+6+54)/(236+9+8+5+714)=3051/972=3.138888...**

I am confident that this** "record" will **have a very short life**.**

Btw, I did not use Charlie's ratios, which might be helpful.
