It is NONE of them as 8 is less than 315 when 8 is divided by 315 it will be less than 1. 8 ÷ 315 ≈ 0.0254 --------------------------------------------- If English is not your first language but Spanish (likely) is, then you may mean 315 ÷ 8 (315 divided by 8), but that is: 315 ÷ 8 = 39.375 which again is none of them. ---------------------------------------------------------------------- However, if there are some missing spaces and slashes in your question, then: 8 ÷ 3 1/5 = 8 ÷ (3×5+1)/5 = 8 ÷ 16/5 = 8 × 5/16 = 5/2 = 2 1/2 which I guess is c.
