Firts, Let

be the repeated decimal that we are trying to convert , so

equation (1)
Next, lets find how many digits are repeating:
It is pretty cleat that 90 is repeating, and 90 has two digits. So we are going to multiply our equation by 100 to move the decimal point two places:

(2)
Subtract equation (1) from equation (2):


Solve for


We can conclude that 10.9090909091... expressed as a rational number, i<span>n the form pq where p and q are positive integers with no common factors, is </span>

Answer:
12
Step-by-step explanation:
if you multiply everything by 5, then you can get rid of the fraction and the equation would now look like this:
x - 40 = 20
and now you can answer this simply
x - 40 = 20
+40 +40
x = 60
and since you multiplied 5 beforehand, now you have to divide by 5 to get the real answer
60 ÷ 5 = 12
therefore, x = 12
