1. In a Gallup poll of 1,038 adults, 540 said that second-hand smoke is very harmful. What is the percentage of adults who said second-hand smoke is very harmful?

540/1038 = ?

Multiply by 100 too.

To find the percentage of adults who said second-hand smoke is very harmful, you need to divide the number of adults who said so by the total number of adults in the Gallup poll, and then multiply the result by 100.

Step 1: Find the number of adults who said second-hand smoke is very harmful, which is given as 540.

Step 2: Find the total number of adults in the Gallup poll, which is given as 1,038.

Step 3: Divide the number of adults who said second-hand smoke is very harmful (540) by the total number of adults in the Gallup poll (1,038): 540 / 1,038 = 0.519.

Step 4: Multiply the result by 100 to convert it to a percentage: 0.519 * 100 = 51.9%.

Therefore, the percentage of adults who said second-hand smoke is very harmful is 51.9%.
