4/5 = 80%
A value of 4/5, or 80%, shows up in everyday situations like getting 4 out of 5 questions correct, finishing 4 of 5 tasks, or having 80% of a battery left. It can also describe a product that received 4 out of 5 stars.
To picture 4/5 quickly, imagine a pizza, chocolate bar, or rectangle divided into five equal parts. Shade four parts and leave one unshaded; that makes it easy to see that the amount is large, but not complete.
A common mistake is treating 4/5 as if it means the same thing as 4 out of 10. The denominator matters because it tells you how many equal parts make up the whole, so 4/5 is much greater than 4/10.
