for .88888888 to infinity, let x=.88888888 then 10x=8.8888888888, so 10xx=9x=8 and x=8/9 which makes sense because .888888 to inf is rational as a repeating pattern, not irrational ALSO x=.7777777 to infinity, then 10x=7.7777777 to infinity so 9x=7 then x=7/9 BUT if x=.99999999999 to infinty and 10x=9.9999999999 then 9x=9/9=1 which does not equal .9999999999 to inf, this implies that the endless decimal .9999999999999 etc is irrational since it cannot apparently be expressed as a quotient of two integers a/b. whatsup with this????
