22/44 = 50%
A fraction like 22/44 shows up in everyday life when something is evenly split between two groups. For example, if 22 out of 44 students choose pizza for lunch, that means 50% of the students choose it.
You can picture 22/44 as one half of a whole, like filling one of two equal sections of a circle or shading half of a row of squares. A quick estimate is to ask whether the top number is about half of the bottom number; here, it is exactly half.
A common mistake is thinking that 22/44 is a large amount just because both numbers look fairly big. The important detail is their relationship, not their size, so this fraction represents one-half rather than 22% or 44%.
