Step-by-step explanation:
30 percent decrease
Step-by-step explanation:
looking at this i know its a percent decrease
so how do we find percent decrease ?
first we subtract the first value 39.39 & the final value 27.57
39.39-27.57 = 11.82
then we divide 11.82 by the first value
like this 11.82÷39.39 = 0.3000
then we multiply what we got by 100
0.3000×100= 30 percent
the way that most people mess up is when they divide sometimes they might do 39.39 divided by 11.82 instead of 11.82÷39.39.
