What is the product of the first ten digits of pi?
When rounded to ten significant figures, the first ten digits of pi are: 3.141592654 The product of these digits is: 3 x 1 x 4 x 1 x 5 x 9 x 2 x 6 x 5 x 4 = 129600 Notwithstanding the eleventh digit of the number, which rounds the tenth digit 3 up to 4, the first ten digits of pi with 3 as the final number would be: 3 x 1 x 4 x 1 x 5 x 9 x 2 x 6 x 5 x 3 = 97200
What fraction will produce this recurring decimal 166166166?
Call this number "x", equal to 0.166166166... 1000x = 166.166166166... x = 0.166166166... Subtract the second equation from the first, you get: 999x = 166 Solving for x: x = 166/999. Note: I multiplied by 1000, because three digits are repeating (and 1000 has 3 digits).
