- ((a-b)/b)*100

I have a measurement with uncertainties for two years. Say

Year 1 Rain : 100mm(80-120mm)

Year 2 Rain : 120mm(103-131mm).

Now I get the percentage change in rain in Year 2 w.r.t Year 1 as 20%. Is there a way to get the uncertainty associated with this percentage change?

Year 1 Rain : 100mm(80-120mm)

Year 2 Rain : 120mm(103-131mm).

Now I get the percentage change in rain in Year 2 w.r.t Year 1 as 20%. Is there a way to get the uncertainty associated with this percentage change?
