Answer 2

You can turn this into a fraction quickly by showing what fraction it is of a power of ten:

.815 = 815/1000

However, that's really messy, so you should simplify. We'll divide both halves by 5:

815/1000 = 163/200

In other cases, you could go further, but it turns out 163 is prime, so you're done!
