A mixed number shows a whole part together with a fractional part. When you write 2 1/3, it means you have 2 whole units plus 1/3 of another unit. That blends both a whole number and a fraction in one written form, so it’s the clear label for this kind of number.

A fraction, like 7/3 or 1/2, doesn’t include a separate whole part written beside the fraction. An improper fraction can represent the same quantity as a mixed number, but it’s written purely as a single fraction. A decimal uses a decimal point, such as 2.333..., to express the value.
