Hello,

If 1/3 of 480 students have traveled overseas, that means (1/3)(480) = 160 students have traveled overseas.

If 15% of the 160 students have been to Australia, then 1 - (0.15) = 0.85 = 85% of the 160 students have not been to Australia.

85% of 160 students = (0.85)(160) = 136 students have not been to Australia.

136 students have not been to Australia.

Hope this helps!
