Answer 1

8.24%

Explanation:

The original number of deaths due to heart disease = 255

The new number of death due to heart disease = 234

$\begin{gathered} \text{Decrease = original number - new number} \\ \text{Decrease = 255-234 = 21} \end{gathered}$$\begin{gathered} \text{Percentage decrease = }\frac{decrease}{\text{original number }}\times100 \\ =\text{ }\frac{21}{255}\times\text{ 100} \\ =\text{ 0.0824 }\times\text{ 100} \\ =\text{ 8.24 percent} \end{gathered}$

Therefore, the percent decrease in deaths due to heart disease this represents is 8.24% (2 decimal place)
