Biology - Hardy Weinberg equation

I don't understand this question:
Galactosaemia is an autosomal recessive disease that hinders the metabolism of the sugar galactose. The disease has an incidence of approximately 1 in 60 000 births. However, in certain Irish Traveller populations, the disease is seen
in 1 in 480 births.
a) Calculate the percentage of the general population that does not carry an allele for galactosaemia. Give your answer to three significant figures.

I know what the equation is, I just don't know how to apply it.
Thank you
