Luis is making chocolate chip cookies. The recipe calls for 1/8 cups of almonds for every 3/4 cup of chocolate chips. If Luis uses 3 cups of chocolate chips, how many cups almonds will he need? Round to the nearest tenths.
If the recipe calls for 1/8 cups of almonds for every 3/4 cup of chocolate chips, then Luis will need (1/8)*(3/4)=<<1/8*(3/4)=0.375>>0.375 cups of almonds for every 3/4 cups of chocolate chips.
If Luis uses 3 cups of chocolate chips, then he will need (0.375/0.75)*3=<<0.375/0.75*3=1.5>>1.5 cups almonds. Answer: \boxed{1.5}.
