108/120 = 90%
A fraction like 108/120, or 90%, can show up in everyday life when 108 out of 120 students submit a permission form. It could also describe a phone battery, a quiz score, or the amount of a project that is finished.
To picture 90% quickly, imagine a group of 10 equal parts with 9 shaded and 1 left unshaded. It is very close to the whole, so you can estimate it as “about nine-tenths” or “just a little less than everything.”
A common mistake is treating 90% as if it means the entire amount is complete. It actually leaves 10% unfinished, missing, or unused, which can still matter when the total number is large.
