Answer:
29.7
Explanation:
To calculate this we need to convert the percentage to a decimal and then multiply. 345% is 3.45, so our math problem is 8.6 x 3.45. If you put that into a calculator you will get 29.67, but since the least precise number is to one decimal place (8.6), I put my answer to one decimal place as well - I rounded 29.67 to the nearest tenth.
