Answer: 5 : 3, 10: 6, 25: 15
Step-by-step explanation: We know from our original ratio that for every 5 peanuts, we have 3 cashews. Therefore 5:3, to get to 6 from 3, we have to double it, and whatever we do to the last number, we have to do to the first, so we get 10:6. We can continue this process for 15:9, 20:12, 25:15
