Answer 1

Answer: The average percentage change per year was 0.3652%.

Explanation:

Given: In 1992, 18.6% of the world population was undernourished.

In 2015, 10.9% of the population was undernourished.

The average percentage change per year will be

`\frac{\text{Percentage in 2015- Percentage in 1992}}{201-1992}\\\\=(18.6\%-10.9\%)/(2015-1992)\\\\=(8.4\%)/(23)\approx0.3652\%`

Hence, the average percentage change per year was 0.3652%.
