Draw fraction sign: >  /  or, ____

Put 427 as the numerator. Then put a 1 in the denominator.

How many numbers you see after the decimal point is the number of zeros you put next to the 1.

Let x = .427272727.....
Then 100x = 42.72727272727
So 100x - 0.3 = 42.427272727....
i.e.
100x - (3/10) = 42.42727272727....
so
100x - (3/10) - x = 42.42727272727.... - .4272727272727...
i.e.
99x - (3/10) = 42
i.e.
99x = 423/10
i.e.
x = 423/990 = 47/110
