How to identify the percent of change as an increase or decrease and how to find the percent change

Uhh well you can find the percentage of change by taking the new part and dividing it by the old one, so it'll be bigger divided by smaller

that's because the 1 is 100% and the decimal is how much it grew by

If it's less than 1 then it's decreasing
