(36/120)100 = 30% why?

i dont understanf why all this happens please explain all steps

To find the percentage decrease, you can follow these steps:

1. Subtract the new price from the original price: $120 - $84 = $36.
2. Divide the decrease in price by the original price: $36 / $120 = 0.3.
3. Multiply the resulting decimal by 100 to convert it to a percentage: 0.3 * 100 = 30%.

So, the item has experienced a 30% decrease in price.
