Question

How do you find the percent change given the original number is 25 and new number is 10?

Answer 1

Percentage change: `color(green)(-60%)`

Explanation:

The change from `25` to `10` is `(10-25)=color(magenta)(-15)`
(change is always measured as "new value" minus "original value").

As a percentage of the original value, `color(magneta)(-15)` is
`color(white)("XXX")color(magenta)(-15)/25 xx100% =color(green)(-60%)`
