Well, isn't that a happy little question! When we have a decimal with a repeating digit, we can turn it into a fraction by setting it equal to x, multiplying by the right power of 10 to shift the repeating part, and subtracting the original number from the shifted number. In this case, 0.32 with the 2 repeating becomes 32/99. Just like that, we've turned a decimal into a lovely fraction!
