Answer: There are 7.67 calories / 12 grams = 0.639 cashews in 1 gram of cashews.
Step-by-step explanation: To find the number of calories in 1 gram of cashews, we divide the total number of calories in 28 grams by 28: 161 calories / 28 grams = 5.75 calories/gram.
Since 12 grams contains 5.75 x 12 = <<12*5.75=69>>69 calories, each cashew contains 69 calories / 9 cashews = <<69/9=7.67>>7.67 calories.
Dividing by the weight of each cashew, we find that there are 7.67 calories / 12 grams = 0.639 cashews in 1 gram of cashews.
