What is the percent of decrease from 77 to 0 ?

When you drop from 77 to 0, that's a whopping 100% decrease! Imagine starting with a delicious pizza and then finding out it’s completely vanished – you effectively lost every slice! So, when we talk percentages, if you’re down to nothing from something, that’s a full-out loss, folks! In practical terms, the formula to calculate percent decrease is: ((original value - new value) / original value) x 100. Plugging in your numbers, it becomes ((77 - 0) / 77) x 100, which gives you that full 100% decrease. It’s like saying, “Nothing left on my plate means everything’s gone!”
