Question

find the absolute change and the relative change in the following case. the assessed number of refugees in a part of the world increased from 7.3 million in 2005 to 17.5 million in 2020. the absolute change is 10.2 million (simplify your answer. type an integer or a decimal.) the relative change is \\(\square\\)% (type an integer or decimal rounded to the nearest tenth as needed.)

Explanation:

Step1: Recall the formula for relative change

The formula for relative change is $\frac{\text{Absolute Change}}{\text{Original Value}} \times 100\%$. We know the absolute change is 10.2 million and the original value (in 2005) is 7.3 million.

Step2: Substitute the values into the formula

Substitute the absolute change (10.2) and the original value (7.3) into the formula: $\frac{10.2}{7.3} \times 100\%$.
First, calculate $\frac{10.2}{7.3} \approx 1.39726$. Then multiply by 100% to get approximately $139.7\%$ (rounded to the nearest tenth).

Answer:

139.7
