Okay so 0.4 is equal to 4/10 (hopefully you know that!) & anything over 1 is itself so i would but 64 over 1.
so now you hace 2 fractions & when dicing fractions you alwas flip the second fraction upside down & then just multiply across.
so if you have
64 4
---- / ----
1 10
you would switch the 2nd one so the 10 would be on top.
so that would give you 64*10 over 1*4
which equals 640/4
& when you simplify that you get 160
so that's your answer(:
