I have a new iPhone 4 from AT&T and it came with the phone number *669 in the Contacts List.

I had the phone dial it * 669 and it connected me to some female computer voice offering to allow me to add additional features to my phone.

What a fraud... more of a sales quick dial line.

To do this you'd have to divide by 669 and multiply by 1000. .669 of an inch is the same as 669 thousandths of an inch

1, 3, 223, 669

669 is a multiple of 3.

3 feet = 1 yard

669 feet = 669 ÷ 3 = 223 yards
