From 77 to 13

would the final answer be 83.1 %?

To find the percentage change from 77 to 13, you can use the following formula:

Percentage change = ((new value - old value) / old value) * 100

In this case, the old value is 77, and the new value is 13. Plugging these values into the formula:

Percentage change = ((13 - 77) / 77) * 100

= (-64 / 77) * 100

= -0.831 * 100

= -83.1

Therefore, the percentage change from 77 to 13 is -83.1%, not 83.1%. The negative sign indicates a decrease in value.
