Find the 100th digit after the decimal point in the decimal expansion of 3/7.
If you solve with long division until the digit repeats you get 0.428571428571... you see that it repeats every 6 digits so 100/6 is 16 remainder 4 so the fourth digit after is 4...2...8...5! Plz tell me if I got this correct!
im 99% sure that the answer is 5, plus someone else solved it and got 5 here: https://www.quora.com/What-is-the-100th-digit-of-3-7-after-the-decimal-point#:~:text=The%20fourth%20digit%20in%203,the%20decimal%20point%20is%205.
