Final answer:
To convert ounces to grams, multiply the number of ounces by 28.35, and then round to the nearest tenth. For 3 ounces, this results in 85.1 grams.
Step-by-step explanation:
To convert ounces to grams, we use the fact that one ounce is approximately equal to 28.35 grams. To find out how many grams are in 3 ounces, we multiply 3 by 28.35:
3 ounces × 28.35 grams/ounce = 85.05 grams
We then round the final answer to the nearest tenth based on the least precise measurement given, which is 0.1. Therefore, 85.05 grams rounded to the nearest tenth is 85.1 grams.
