Answer 1

George has 2/5 of U.S magenets

Answer 2

we have that
4/5 of the magnets in George’s collection -------------------- > are flags
1/2 of those flags --------------------- > are U.S flags
4/5*(1/2)=4/10=2/5

this means that
4/5------------ >2/5+2/5
therefore
2/5---------------- > are U.S flags

the answer is 2/5
