Two properties of minerals that can be expressed in numbers are hardness and specific gravity. Hardness is usually determined using the Mohs scale and is expressed as a number between 1 (softest) and 10 (hardest). Specific gravity is the ratio of a mineral's density compared to the density of water and is expressed as a number.

What are numbers that can be expressed as a fraction?
Numbers that can be expressed as fractions consisting of two integers are rational numbers. sqrt(2)/3 or pi/4 are fractions but they are not rational.
A number that can be expressed as a ratio of 2 integers?
Rational numbers.
What is a mangle number?
A mangle number is a term used in mathematics to describe a number that can be expressed as the sum of the digits of its own factorial. For example, 1 and 2 are considered mangle numbers because (1! = 1) and (2! = 2), and the sum of their digits equals the numbers themselves. However, as numbers increase, finding mangle numbers becomes increasingly rare. The concept is part of recreational mathematics and explores interesting properties of numbers.
What sets of numbers does 8 belong to?
The number 8 belongs to several sets of numbers, including the natural numbers (1, 2, 3, ...), whole numbers (0, 1, 2, 3, ...), integers (..., -2, -1, 0, 1, 2, ...), rational numbers (fractions that can be expressed as a/b where a and b are integers), and real numbers (which include both rational and irrational numbers). Additionally, 8 is an even number and a perfect cube, as it can be expressed as (2^3).
Can every prime number be expressed as the product of 2 prime numbers?
No, none can.

What is irratoinal numbers?
An irrational number can not be expressed as a fraction such as the square root of 2
Can every prime number be expressed as the product of 2 prime numbers?
No, none can.
What are number sets?
Number sets are collections of numbers that share specific properties or characteristics. Common examples include natural numbers (positive integers), whole numbers (natural numbers including zero), integers (whole numbers and their negatives), rational numbers (fractions of integers), and irrational numbers (numbers that cannot be expressed as fractions, such as √2 or π). These sets help organize numbers and facilitate mathematical operations and concepts.
Difference between rational and irrational?
Rational numbers can be expressed in the form p/q (where q is not equal to zero). Irrational numbers cannot be expressed in this form. For example, the square root of 2 cannot be expressed as p/q.
What is the role of rational and irrational number plays in modern day calculation?
Rational numbers can be expressed as fractions whereas irrational numbers can't be expressed as fractions such as the square root of 2
Is the difference of any 2 rational numbers a rational number?
Yes it is. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
