The description for my question is basically a math question and I don't get this. It was question on my homework and I don't know if this was a trick question but I need help

Answer 1

It is a matter of what question you want to answer:

 

To find a DECREASE of 25%, you multiply by 0.25

 

To find the amount REMAINING after a 25% decrease, you multiply by 0.75
