Answer:

12545454/100000000

Explanation:

To express 0.12545454 in the form of p/q, where p and q are integers, we can follow these steps:

1. Let x = 0.12545454.

2. Multiply x by a power of 10 to remove the repeating decimal part. Since there are two digits repeating, we will multiply by 100 to get rid of the repetition.

x * 100 = 12.545454.

3. Subtract x from the product obtained in step 2 to eliminate the repeating part.

100x - x = 12.545454 - 0.12545454 = 12.42.

4. Now, we have the equation 99x = 12.42. Divide both sides by 99 to solve for x.

x = 12.42 / 99 = 0.125454545...

5. Notice that the decimal part in step 4 is the same as the original decimal part (0.12545454). Therefore, we can express 0.12545454 as a fraction p/q.

p/q = 0.12545454/1 = 12545454/100000000.

So, 0.12545454 can be expressed in the form of p/q as 12545454/100000000.
