I am going to assume you mean that 4589 is repeating, and that the 29 is repeating in the second decimal.
If you have a repeating decimal, the easiest thing to do is represent it in a fraction over however many 9's are equal to the number of repeating decimal places. So, .4589 repeating = 4589 / 9999. The last part is to simplify this fraction as much as possible, in which this fraction is actually as simplified as it can get.
7.29 (29 repeating) is 7 and 29/99, or as an improper fraction would be 722 / 99, and this fraction is also in reduced form.

It's not clear where your repeating decimals repeat. Supposing that they are 0.458945894589... and
7.2929292929... then:
x = 0.45894589...
10000 x = 4589.45894589...
10000 x = 4589 + x
9999 x = 4589
x = 4589/9999 which is in lowest terms. Likewise:
y = .2929...
100 y = 29.2929...
100 y = 29 + y
99 y = 29
y = 29/99 , so 7 + y =
7 29/99

These are not repeating decimals, but here is how to represent them as ratios of integers:
0.4589 = 4589/10000
7.29 = 729/100
