I have a pie chart showing:
Boy: 80%
Girl: 20%
How to say the fraction of girls, "one in five is girl" or "one in five are girls"?

I would use the past tense if the statistic is being reported as the conclusion of the survey:
One in five of the people in the survey was a girl.
One in five of the people surveyed were female.
Twenty percent of the people surveyed were girls.
When merely reading from a graph, I would use the present tense:
Four out of five of the people on this pie chart are boys.
Four out of every five people on this pie chart are male.
One-fifth would be how I'd state the 1 divided by 5 that is the fraction.
Alternatively, you could state the ratio is "One girl to every four boys" to convey that information.
