To convert the repeating decimal 0.\overline{8} into a rational number, we can use the concept of geometric series. Let's denote x as 0.\overline{8}:
x = 0.888...
Now, if we multiply both sides of the equation by 10, the decimal point will shift:
10x = 8.888...
To eliminate the repeating part, we subtract the original equation from the multiplied equation:
10x - x = 8.888... - 0.888...
Simplifying the expressions:
9x = 8
Dividing both sides by 9:
x = 8/9
Therefore, 0.\overline{8} is equal to the rational number 8/9.

To convert 0.82¯¯¯¯¯ to a rational number, you would set x equal to 0.82¯¯¯¯¯ and then multiply both sides of the equation by what number?
To convert 0.82¯¯¯¯¯ to a rational number, we need to set x equal to 0.82¯¯¯¯¯ and multiply both sides of the equation by the appropriate number to eliminate the repeating part.
Let's denote x as 0.82¯¯¯¯¯:
x = 0.82¯¯¯¯¯
To eliminate the repeating part, we multiply both sides of the equation by 100:
100x = 82.828282...
Now, subtracting the original equation from the multiplied equation:
100x - x = 82.828282... - 0.82¯¯¯¯¯
Simplifying the expressions:
99x = 82
Dividing both sides by 99:
x = 82/99
Hence, 0.82¯¯¯¯¯ is equal to the rational number 82/99.

Apologies for the incorrect response in my previous message.
To convert 0.82¯¯¯¯¯ to a rational number, we can follow these steps:
Let's denote x as 0.82¯¯¯¯¯:
x = 0.82¯¯¯¯¯
Since the digit 8 repeats, we can represent it as an infinite geometric series. In this case, the first term would be 8/10 and the common ratio would be 1/10.
The formula for the sum of an infinite geometric series is:
S = a / (1 - r)
Plugging in the values, we have:
x = (8/10) / (1 - 1/10)
Simplifying:
x = (8/10) / (9/10)
To divide fractions, we multiply the first fraction by the reciprocal of the second:
x = (8/10) * (10/9)
Now, we can cancel out the common factor of 10:
x = 8/9
Therefore, 0.82¯¯¯¯¯ is equal to the rational number 8/9.
