I am stuck on a "percent difference" problem where I have the following:
(2.75 - 2.25) / 2.75 then multiplying by 100.
Doing this long hand, I got:
0.50 / 2.75
I then took away the decimal to do 050 into 275, which = 55.
Adding the decimal back in, I got 5.5. 5.5 * 100 = 550.
I confirmed this with an online long division calculator.
But when I use Symbolab or a regular calculator, it comes to
0.1818 * 100 = 18.18.
What am I doing wrong?
I didn't find the right solution from the Internet.
