Luis is making chocolate chip cookies. The recipe calls for (1)/(8) cup of almonds for every (3)/(4) cup of chocolate chips. If Luis uses 3 cups of chocolate chips, how many cups of almonds will he need? Round to the nearest tenth.

Since for every (3)/(4) cup of chocolate chips, Luis needs (1)/(8) cup of almonds, for 3 cups of chocolate chips he will need:

(3)/(4) * 3 = <<(3)/(4)*3=2.25>>2.25 cups of almonds. Answer: \boxed{2.3}.
