Dont ask me why...I cant really explain it...but if u have 1 repeating decimal, u put it over 9. If u have 2 repeating decimals, u put it over 99....3 repeating decimals, put it over 999.
0.27 (repeating) is an irrational number and can be transformed into a rational number using a calculator. In this case, we input 7 more than ten times after 2 and get the rational number 5/18. The answer to this problem therefore is 5/18.
