To get rid of the infinite chain of 26s
x = .26262626....
100x = 26.26262626....
The right sides of the equations are the same. When we subtract, we get rid of .26262626.... and that is what we want if we want to convert a non terminating repeating decimal to a fraction. Else with infinite .26s, how many zeroes will you put in the denominator to convert it to a fraction (i.e. say 2.6 = 26/10, .2626 = 2626/10000, what about .26262626... infinite?)
