I don't know how to put a bar over a number number so I'll see if I can explain it to you.
0.7353535... Find the repeating pattern of digits, here it's 35 after the first digit (7), and put a bar over the first set of repeating digits then discard the remaining digits to the right but keep the digit to the left of the repeating sequence.

with a bar over the 42
with a bar over the 126
