Since this is a math section, let's make an equation!
First of all, the current ratio is NOT 7:5. It is 12:10 or 6:5.
Now, the equation for the ratio is x+2:x, right?
And what happens when x gets very large? x+2:x is never eqivalent to 1:1. It keeps getting closer, but never reaches it.

Firstly,the ration id 6:5 (e.g 12:10)
A ratio of 7:7 or 1:1 means that the 2 numbers are the same. This can never happen while both you and your sister are living.
If you outlive her by 2 years, at that moment the ration will be 7:7

No. The ratio will aproach 1 as your ages become infinite
10 & 12: 5:6
20 & 22: 10:11
30 & 32: 15:16
100 & 102: 50:51
etc but it will never reach 1
