if you solve 6 × 3/8 you should get 18/8 which then simplifies to 9/4. if you go though each answer choice solving each problem you should get 9/4 and if you dont then that is not the answer. the first 2 answer choices equal 16 which is not 9/4 and the 4th answer choice will give you 4 and 6 × 8/3 gives you 48/3 which gives you 16 so only the 3rd and last answer choices are correct
