25%= 25/100 = 1/4
Percent means over hundred. How many cents are in a dollar a hundred. So per-cent is over-hundred.
Total number pages of book = T
T/4 = 40
Multiply both sides by 4
You get
T=160
The book is 160 pages long.

Just practice. You will be a pro with practice. I was absolute trash at doing problems like these when I was younger. Now after doing thousands like them, I am a pro. Not a genius a pro.
