Data that can't be expressed in numbers is called qualitative data, which includes descriptions and observations. Color, texture, emotions, and shape are examples of qualitative data.
Qualitative (quantitative are observations that can be expressed numerically)

Numbers that can be expressed as a ratio are called rational numbers.
There are numbers which cannot be expressed as ratios of two integers. These are called irrational numbers.
Observations that deal with descriptions that cannot be expressed in numbers are called qualitative observations.

They are called rational numbers that can be expressed as fractions
They are called irrational numbers; numbers that can be expressed as a ratio of integers are called rational numbers. Some common irrational numbers are pi (3.14159...) and the square root of two.
All rational numbers can be expressed as fractions whereas irrational numbers can't be expressed as fractions.
Numbers expressed using exponents are called powers. When writing a number expressed as an exponent, the number is called the base. For example, in 23 two is the base.
Such numbers are called rational numbers.
