To convert 0.51 repeating to a fraction, we can represent it as x = 0.515151..., where the repeating decimal part is 51. Let y represent the non-repeating part, which is 0.5 in this case. To convert x to a fraction, we subtract y from x, which gives us 0.51 - 0.5 = 0.01. Next, we divide this difference by the same number of nines as the repeating part, which is 2 nines in this case, since there are two digits in the repeating part (51). Therefore, 0.51 repeating as a fraction is 1/2 + 1/99 = 49/99.
