What is the percent of change from 125 centimeters to 87.5 centimeters?

For my calculations, it suppose to be 30%.

I hope this is the right answer for you.

Percent change formula is change / original x 100.

To find the change we subtract 87.5 from 125, giving us 37.5.
We already know the original, 125.

So we do 37.5 / 125, which is 0.3, then multiply it by 100, which gives us 30.

The answer is that there was 30% decrease.

Hope this helps :)

Iknow one of the answers is a and maybe b but not 100% sure about b
