GPT 3.5
To show that 0.5 repeating as a fraction is equal to 5/9, we can manipulate the decimal to convert it to a fraction.
Let x = 0.5 repeating
Multiplying x by 10 (to shift the decimal point to the right once) gives:
10x = 5.5555...
Now, we can subtract x from 10x to get:
10x - x = 9x = 5.5555... - 0.5555... = 5
Therefore, x = 5/9, which means that 0.5 repeating as a fraction is equal to 5/9.
