How would we solve problems such as 16 and 17? These problems do not repeat in numbers such as 0.235235235.

Like for 16, how would we put that in geometric form first?

I tried 0.122 + 0.0012 + 0.000012 ect but cannot find out how to get a fraction that will give that answer.

Please help me on this. Thank you.
