Answer 1

Common formula for determining %change is

$\pink{\%change = \frac{final - initial}{initial} } \times 100$

$\%change = \frac{3 - 1}{1} \times 100 \\ = 200\%$

The answer you are telling would be obtained if

If we change

from

3 to 1

$\%change = \frac{1 - 3}{3} \times 100 \\ - \frac{2}{3} \times 100$

Negative sign Informs us that there is % decrease

$= \frac{200}{3} \% \\ \\ = 66.67\%$
