The ratio of two integers P and Q can be expressed as P : Q or P/Q. In both cases, you may divided P and Q by their greatest common factor so as to express the ratio in its simplest form. Alternatively, you may multiply both by some number so that the first part is 1 or the second part is 1 (both unit ratios), or the second part is 100 (a percentage), or a million (part per million) and so on.
There is none
Because that is the definition of irrational numbers: They are the numbers that cannot be written as a ratio of two integers! A fraction is a ratio of two integers.
431/100
Can be an integer, a rational number or undefined.
A rational number cannot be expressed as a ratio of two integers, the second of which is positive.
The ratio of two integers, p and q where q is not 0, can be expressed as p:q or p/q.
Yes, -0.15 is a rational number. A rational number is any number that can be expressed as a ratio of two integers, where the denominator is not zero. In this case, -0.15 can be expressed as -15/100, which is a ratio of two integers (-15 and 100). Therefore, -0.15 is a rational number.
One possibility is 27/1.
2/3
a ratio of integers
A number that cannot be expressed as the ratio of two integers is known as an irrational number.
Not quite. A rational number is a ratio and each rational number is a ratio of specific pairs of integers - not ANY two integers. And, of course, 0 is not allowed on the denominator.
ratio of two integers, p/q where q is not equal to zero.
Any number that can be expressed as the ratio of two integers is a rational number.
The ratio is not defined.
