The fraction 70/97 is equal to 72.16% when converted to a percentage and rounded to two decimal places. This means that if you had 97 items and took 70 of them, you'd have about 72% of the total. It's a bit more than seven-tenths or 70% of the whole, which might be easier to picture.
While 72.16% isn't a common percentage you'd see every day, it's still useful to understand. For example, if you got 70 questions right out of 97 on a test, you'd score about 72%. Or if 70 out of 97 people liked a new product, the company could say it had a 72% approval rating. Knowing how to work with these kinds of numbers can help in many real-world situations.
