How do you calculate the percentage change between two numbers?

To calculate the percentage change between two numbers, you can find the difference between the two numbers, divide that number by the initial value, and then multiply the result by 100. For example, if you want to find the percentage change between 360 and 700, you would first find the difference (700 - 360 = 340), then divide 340 by 360 (the initial value) to get 0.94, and finally multiply by 100 to get 94%.
