0.44444444444 (repeated) or 4/9 The simplest form of that is 0.4 which is 44/99 or 4/9
3*3*3*3=81
These would numbers like 1122, 9988, 2233.There are 81 such numbers. (90 if you allow 0011, 0022, ...)
81% of 81= 81% * 81= 0.81 * 81= 65.61
81
The answer is 1,3,9,27,81. 81*1=81 3*27=81 9*9=81 27*3=81 81*1=81
It is 81*81*81. Which is 531,441.
9046. 20 ÷ 11 = 1.81... With the 81 repeating forever. So the sum of the first 2011 digits is the first digit plus the next 2010 digits which are "81" repeated 1005 times. Sum = 1 + (8 + 1) x 1005 = 9046
