Let's call the repeating decimal x.
If we take away the repeating part, we get:
10x = 0.01
If we move the decimal point two places to the right, we get:
100x = 1
Now we can subtract the two equations:
100x - 10x = 1 - 0.01
90x = 0.99
To get x by itself, we divide both sides of the equation by 90:
x = 0.99 / 90
Simplifying the fraction:
x = 11 / 1000
Therefore, the repeating decimal 0.01 with a line over the "01" can be written as the fraction 11/1000.

Let's call the repeating decimal x.
If we take away the repeating part, we get:
100x = 0.01
If we move the decimal point two places to the right, we get:
10000x = 1
Now we can subtract the two equations:
10000x - 100x = 1 - 0.01
9900x = 0.99
To get x by itself, we divide both sides of the equation by 9900:
x = 0.99 / 9900
Simplifying the fraction:
x = 1 / 100
Therefore, the repeating decimal 0.01 with a line over the "01" can be written as the fraction 1/100.
Alternatively, if we observe that the repeating decimal is 0.01010101..., we can write it as a geometric series:
0.01010101... = 0.01 * (1 + 0.01 + 0.0001 + ...)
Using the formula for the sum of an infinite geometric series:
Sum = a / (1 - r)
where "a" is the first term and "r" is the common ratio, we can substitute in the known values:
Sum = 0.01 / (1 - 0.01) = 0.01 / 0.99
Simplifying the fraction:
0.01 / 0.99 = 1/100
Therefore, the repeating decimal 0.01 with a line over the "01" can also be written as the fraction 1/100.

Let's call the repeating decimal x.
If we take away the repeating part, we get:
10x = 8.85
If we move the decimal point two places to the right, we get:
100x = 88.5
Now we can subtract the two equations:
100x - 10x = 88.5 - 8.85
90x = 79.65
To get x by itself, we divide both sides of the equation by 90:
x = 79.65 / 90
Simplifying the fraction:
x = 8865 / 9900
To simplify the fraction further, we can divide both the numerator and denominator by their greatest common divisor, which is 15:
x = 591 / 660
Therefore, the repeating decimal 8.85 with a line over the "85" can be written as the fraction 591/660.
